MCU
The Z8 Encore!TM 8K/4K MCU is member of a family of ZiLOG micro-
controller products based upon the 8-bit eZ8 core CPU. The Flash in-cir-
cuit programming capability allows for faster development time and
program changes in the field. The eZ8 core CPU is upward compatible
with existing Z8®instructions. The rich peripheral set of the Z8 Encore!
8K/4K makes it suitable for a variety of applications including motor con-
trol, security systems, home appliances, personal electronic devices, and
sensors.
The evaluation board contains circuitry to support and present all the fea-
tures of the Z8 Encore! 8K/4K. The main features of the Z8 Encore! 8K/
4K are:

munication between the Z8 Encore! 8K/4K and IrDA transceivers. Infra-
red communication provides secure, reliable, low-cost, point-to-point
communication between PCs, PDAs, cell phones, printers and other infra-
red enabled devices.
Crystal Oscillator
The evaluation board ships with an 18.432MHz Crystal Oscillator (Y1).
If you want to change the change the Crystal Oscillator you are required
to change the Clock Frequency in for ZDSII. The frequency settings can
be found at Project > Settings > Debugger > ZDB: Configure ZDB Driver: Clock
Frequency. See the Z8Encore! Product Speciification for supported fre-
quencies.
Power and Communication Interfaces
Table 1 provides jumper information concerning the shunt status, func-
tions, devices and defaults affected of jumpers JP3 and JP4.
