Overview
Zilog’s Z8F3224 ZMOTION Development Kit provides a general-purpose platform for evaluating the
capabilities and operation of the ZMOTION Engine Library using the Z8F3224 Series of microcontrollers.
This kit is equipped with two Z8F3224 MCUs –one configured for Low Power operation and one
configured for Normal Power operation and comes complete with various lenses to test the ZMOTION
Engine Library for multiple applications.
Zilog’s ZMOTION Engine Library provides an integrated and flexible solution for Passive Infra-Red (PIR)-
based motion detection applications. The Software library is comprised of the PIR sensor signal
processing algorithms for motion detection, transient and noise detection, white light detection, and
several other motion-related functions to be integrated with the user’s application code.
An Application Programming Interface (API) allows the application code to configure, control, and monitor
the Library in real time. API configuration parameters allow the Engine operation to be optimized for the
particular lens and pyro electric sensor being used in the application. This allows the designer to create
their own application-specific software while taking advantage of Zilog’s ZMOTION Motion Detection
technology.
For more information about the operation of the ZMOTION Library, refer to ZMOTION Engine User
Manual (UM0275).

The MCU’s share the same PIR sensor, so only one device may be used at a time. SW4 (Active
MCU Selection) is used to select the active MCU. The unselected MCU is powered off.
•The LP MCU is in the Low Power configuration.
•The NP MCU is in the Normal Power configuration.
For a demonstration with the pre-programmed application, perform the following steps:
1. Install the VCOM USB driver included with the ZMOTIONL400ZCOG_1.0 installation file by right-
clicking on the .exe file and selecting Run as administrator. This driver is located in the Drivers
folder.
-Zilog_VCOM_Install.x64.exe: 64-bit Windows
-Zilog_VCOM_Install.x86.exe: 32-bit Windows
-The Device Driver will be installed as (Zilog USB Serial Device) in Device Manager under
Ports (COM & LPT)
2. Set SW4 to select the active MCU configuration (LP or NP).
3. Install the ZNCL10IL lens on the PIR sensor.
4. Ensure that each jumper is installed for J4 (2:3 shunt) and J9 (2:3 shunt). Active device is
enabled on SW4.
5. Ensure that R16 is adjusted on a fully clockwise direction. This shall allow NP_VDD_IN to have
the same voltage level as VCC_T.
6. With the USB A (male) to Mini-B cable, connect Port P1 on the Development Board to a USB
port on the development PC or other suitable power source to apply power to the Development
Board.
–Alternatively, power can be supplied from a bench type power supply using J12 and J13.
An input of 5V to 12V is supported.
When power is first applied, the status LED will blink until the PIR sensor is stable. When the PIR sensor
is stable, the status LED will turn off and blink when motion is detected.
If the USB interface is connected to a PC, a terminal emulation program like RealTerm or CoolTerm can
be used to observe the motion status events. Set the serial interface to 57600bps, N, 8, 1.
Refer to the Sample Applications section to learn more about specific MCU operations.

UM029501-0321 MCU CURRENT MEASUREMENT
User Manual
10
MCU Current Measurement
The MCU current consumption can be easily measured by removing the shunt on J4 (LP Current) or J9
(NP Current) and connecting an ammeter on the respective positive (+) and negative (–) header pins.
Operating Voltage Adjustment
The MCU operating voltage can be adjusted from 2.0V to 3.5V by the R33 potentiometer. Turn the
potentiometer clockwise to decrease the voltage. The operating voltage can be measured from the J11
header (labeled VCC_T).
UART Interface
The MCU UART can be connected to the Serial to USB converter (U8) and/or directly available as TTL
signals via J10 (NP MCU) or J5 (LP MCU). Use the jumpers on J17 (NP MCU) and J16 (LP MCU) to
select the desired connection.
Table 5. LP MCU UART Connections
Use caution when using a separate Serial to USB converter cable connected to J10 or J5. The Z8F3224
supply voltage (VCC_T) selected by R33 must match the drive level provided by the cable. The sample
applications provided avoid this issue as follows:
•Txd: Configured as Open Drain without an internal pull up. The pull up resistor should be
provided on the Rxd (cable) side.
•Rxd: Internal pull-up resistor connected to VCC_T is enabled. The Txd side (cable side) should
drive using Open Drain.
•The Serial to USB chip (U8) on the ZMOTIONL400 board is configured in this manner.
•Failing to follow this precaution can cause unexpected behaviour and inaccurate current
measurement reading through J9 (NP MCU) or J4 (LP MCU).

Sample Applications
Table 6 lists four sample application projects that are included with the ZMOTIONL400ZCOG_1.0
installation file. Contact Zilog Technical Support for additional sample projects.
The LP and NP MCUs on the Development Board come preloaded with the ZM_LP_Basic and
ZM_NP_Basic projects. To load a different project, refer to the Using ZDS-II to Debug a Project section
on page 16.
The Z8 Encore! family of MCUs supports three operating modes:
•Run –In this mode, the CPU is running and all peripherals/clock sources can be enabled (normal
running mode).
•Halt –In this mode, the CPU is not running and all peripherals/clock sources can be enabled.
Exit via interrupt.
•Stop –In this mode, the CPU is not running and some peripherals/clock sources can be enabled.
Exit via Stop Mode Recovery (SMR).
Stop mode provides the lowest current consumption and is used in the ZM_LP_Basic and
ZM_LP_Command projects. The ZM_NP_Basic and ZM_NP_Command projects use Halt mode to
reduce current consumption.
However, debugging operations are limited when using Stop mode. To use the full debugger with the
ZM_LP_Basic and ZM_LP_Command projects, the following configuration definition is included in the
Sleep.h file that enables the use of Halt mode in place of Stop mode.
#define USE_STOP_MODE
Set this definition to 0 and rebuild the project before to use Halt mode in place of Stop mode. Set this
definition to 1 to use Stop mode. Current consumption will be higher when using Halt mode.

ZM_LP_Basic
This project uses the Low Power MCU configuration to provide motion detection with ZMOTION
Digital PIR validation.
The MCU stays in Low Power Stop mode until a motion event is detected by the analog PIR
interface. When the MCU wakes up it runs the ZMOTION Engine on the PIR signal to validate the
motion event.
When the motion event is validated, the status LED is flashed, and a message is sent via the
VCOM USB serial interface (connected to UART0 on the LP MCU).
Typical current consumption is <15uA @ 3.3V
Sliding SW4 to the LP position causes the NP MCU to be powered off and powers on the LP MCU.
The following status messages will be displayed on the terminal after power on.

The MCU normally stays in Stop mode to conserve power. Each time it wakes up, a status
message is sent to indicate the reason for the wake up. Table 7 lists these status message
descriptions.
Note: In Table 7, ‘*’indicates MCU wake up and ‘.’indicates MCU returning to Stop mode. When
Motion Detected status is sent, an ASCII BELL character (0x07) is also sent. Some terminal
applications can interpret this and provide an audible indication of motion detection
