1 GETTING STARTED
1.1 GENERAL
The TERIDIAN Semiconductor Corporation (TSC) 71M6534H Demo Board is a demonstration board for
evaluating the 71M6534H device for 3-phase electronic power metering applications. It incorporates a 71M6534
or 71M6534H integrated circuit, peripheral circuitry such as a serial EEPROM, emulator port, and on board
power supply as well as a companion Debug Board that allows a connection to a PC through a RS232 port. The
demo board allows the evaluation of the 71M6534 or 71M6534H energy meter chip for measurement accuracy
and overall system use.
The board is pre-programmed with a Demo Program in the FLASH memory of the 71M6534/6534H IC. This em-
bedded application is developed to exercise all low-level function calls to directly manage the peripherals, flash
programming, and CPU (clock, timing, power savings, etc.).
The 71M6534/6534H IC on the Demo Board is pre-programmed with default calibration factors.
1.2 SAFETY AND ESD PRECAUTIONS
Connecting live voltages to the demo board system will result in potentially hazardous voltages on the demo

powered with their 5VDC power supplies.

71M6534H Demo Board User’s Manual
Page: 11 of 86 © 2005-2007 TERIDIAN Semiconductor Corporation V2-0
Figure 1-1: TERIDIAN D6534T14A2 Demo Board with Debug Board: Basic Connections
The D6534T14A2 Demo Board block diagram is shown in Figure 1-2. It consists of a stand-alone meter Demo
Board and an optional Debug Board. The Demo Board contains all circuits necessary for operation as a meter,
including display, calibration LED, and internal power supply. The Debug Board provides magnetic isolation
from the meter and interfaces to a PC through a 9 pin serial port. For serial communication between the PC and
the TERIDIAN 71M6534H, the Debug Board needs to be plugged with its connector J3 into connector J2 of the
Demo Board.
Connections to the external signals to be measured, i.e. AC voltages and current signals derived from shunt
resistors or current transformers, are provided on the rear side of the demo board (see Figure 3-1).
Caution: It is recommended to set up the demo board with no live AC voltage
connected, and to connect live AC voltages only after the user is familiar with
the demo system.
All input signals are referenced to the V3P3 (3.3V power supply to the chip).

1.7.1 POWER SUPPLY SETUP
There are several choices for meter power supply:
•Internal (using phase A of the AC line voltage). The internal power supply is only suitable when phase A
exceeds 220V RMS.
•External 5VDC connector (J1) on the Demo Board
•External 5VDC connector (J1) on the Debug Board.
The power supply jumper JP1 must be consistent with the power supply choice. JP1 connects the AC line
voltage to the internal power supply. This jumper should usually be left in place.
1.7.2 CABLE FOR SERIAL CONNECTION (DEBUG BOARD)
For connection of the DB9 serial port to a PC, either a straight or a so-called “null-modem” cable may be used.
JP1 and JP2 are plugged in for the straight cable, and JP3/JP4 are empty. The jumper configuration is reversed
for the null-modem cable, as shown in Table 1-1.
Cable
Configuration Mode Jumpers on Debug Board
JP1 JP2 JP3 JP4
Straight Cable Default Installed Installed -- --
Null-Modem Cable Alternative -- -- Installed Installed
Table 1-1: Jumper settings on Debug Board
JP1 through JP4 can also be used to alter the connection when the PC is not configured as a DCE device.

Example: )08$$$$ Reads data words 0x08, 0x0C, 0x10, 0x14
)04=12345678=9876ABCD Writes two words starting @ 0x04
MPU or XDATA space is the address range for the MPU XRAM (0x0000 to 0xFFF). All MPU data words are in
4-byte (32-bit) format. Typing ]A? will access the 32-bit word located at the byte address 4 * A = 0x28. The
energy accumulation registers of the Demo Code can be accessed by typing two Dollar signs (“$$”), typing
question marks will display negative decimal values if the most significant bit is set.
Commands for DIO RAM (Configuration RAM) and SFR Control:
R DIO AND SFR CONTROL Comment
Description: Allows the user to read from and write to DIO RAM and special function registers (SFRs).
Usage: R [option] [register] … [option]
Command
combinations:
RIx… Select I/O RAM location x (0x2000 offset is
automatically added)
Rx… Select internal SFR at address x
Ra???...
Read consecutive SFR registers in Decimal, starting at
address a
Ra$$$...
Read consecutive registers in Hex, starting at address
a
Ra=n=m…
Set values of consecutive registers to n and m starting
at address a
Example: RI2$$$ Read DIO RAM registers 2, 3, and 4 in Hex.
DIO or Configuration RAM space is the address range 0x2000 to 0x20FF. This RAM contains registers used for configuring
basic hardware and functional properties of the 71M6534/6534H and is organized in bytes (8 bits). The 0x2000 offset is
automatically added when the command RI is typed.
The SFRs (special function registers) are located in internal RAM of the 80515 core, starting at address 0x80.

Commands for EEPROM Control:
EE EEPROM CONTROL Comment
Description: Allows user to enable read and write to EEPROM.
Usage: EE [option] [arguments]
Command
combinations:
EECn EEPROM Access (1 ÆEnable, 0 ÆDisable)
EERa.b Read EEPROM at address 'a' for 'b' bytes.
EESabc..xyz Write characters to buffer (sets Write length)
EETa Transmit buffer to EEPROM at address 'a'.
EEWa.b...z Write values to buffer
CLS Saves calibration to EEPROM
Example: EEShello
EET$0210
Writes 'hello' to buffer, then transmits buffer to
EEPROM starting at address 0x210.
Due to buffer size restrictions, the maximum number of bytes handled by the EEPROM command is
0x40.
Auxiliary Commands:
Typing a comma (“,”) repeats the command issued from the previous command line. This is very helpful when
examining the value at a certain address over time, such as the CE DRAM address for the temperature (0x40).
The slash (“/”) is useful to separate comments from commands when sending macro text files via the serial
interface. All characters in a line after the slash are ignored.
Commands controlling the CE, TMUX and the RTM:
C COMPUTE ENGINE
CONTROL Comment
Description: Allows the user to enable and configure the compute engine.
Usage: C [option] [argument]
Command
combinations:
CEn Compute Engine Enable (1 ÆEnable,
0 ÆDisable)
CTn
Select input n for TMUX output pin. n is interpreted as
a decimal number.
CREn RTM output control (1 ÆEnable, 0 ÆDisable)
CRSa.b.c.d Selects CE addresses for RTM output
Example: CE0
Disables CE, followed by “CE OFF” display on LCD.
The Demo Code will reset if the WD timer is enabled.
CT3 Selects the VBIAS signal for the TMUX output pin
