Installation
This chapter describes the installation of hardware and software tools for
the Z8 Encore! Evaluation Kit. Also describes setting up the evaluation
board, substituting plug configurations of the universal 9 V DC power
supply, and installing the ZDS II—IDE Z8 Encore! software.
Setting up the Evaluation Board
The PC communicates with the Z8 Encore! Flash MCU Evaluation board
using the serial port of the PC. A Z8 Encore! Smart Cable converts the
RS-232 signals into the 3.3 V bidirectional open-drain signal needed to
communicate with the on-chip debugger of the eZ8. This Z8 Encore!
Smart Cable is a small circuit board with an attached cable and a six-pin
right angle female connector that attaches to the evaluation board.

64K Series Flash Microcontrollers Product Specification
LED Array
The LED array display user information. There are four 7 x 5 LED
matrixes. To light up an LED dot the appropriate Anode bit must be 1, and
the correlated Cathode must be 0. All Anodes are addressed by Port G,
and Cathodes are addressed by Port E. Every LED Matrix is addressed by
separate pair of registers. Each register pairs is addressed by a bit of Port
E or Port G. Table 1 through Table 4 describe how to address each Anode
and Cathode of D1 through D4.
The Z8 Encore! is compatible with I2C protocol (in this case the
PCA8550). The I
serial data (SDA) line and a serial clock (SCL) line.
2
The I
C Controller operates in Master mode to transmit and receive data.
Having a PCA8550 on board enables configuration of the Expansion
Module. The PCA8550 is a 4-bit multiplexer that selects four bits of data
either from a non-volatile register or from the input pins. In this case four
input pins are left unconnected and only a non-volatile register is selected
as a source of data. Only three bits are used. Currently this chip is not
used by the software provided with the board, so you can use it to your

advantage. The configuration register (Table 4) is available at the address
0x9C for Write operation and 0x9D for Read operation on the PCA8550
device. For more details on programming this device, refer to PCA8550

C Address for Configuration Register on the PCA8550 (U2)
).
SPI Interface
The SPI allows the Z8 Encore! to exchange data between other peripheral
devices such as EEPROMs, ADC, and ISDN devices. The SPI is a fullduplex, synchronous, character-oriented channel that supports a four-wire
interface.
16
To work with SPI interface for temperature/sensor types of applications,
DS1722 Digital Thermometer was incorporated into the board. The serial
mode is SPI. For more details on programming the device, refer to
DS1722 Product Specification.
IrDA Transceiver
The Z8 Encore! contains two fully-functional, high-performance UARTs
with Infrared Encoder/Decoders (Endec). The Infrared Endec is integrated with an on-chip UART to allow easy communication between the
Z8 Encore! and IrDA transceivers. Infrared communication provides
secure, reliable, low-cost, point-to-point communication between PCs,
PDAs, cell phones, printers and other infrared enabled devices.

Smart Cable
The Z8 Encore! Smart Cable enables communication with the Host
computer. The Z8 Encore! Smart Cable converts a one-wire interface into
a two-wire (TxD and RxD RS-232-like interface with RS-232 levels).

Expansion Module Interface
The Expansion Module Interface allows addition of any plug-in modules.
The Expansion Module Interface brings out the signals from the Z8

Interface. Tables 5 and Tab le 6 list the signals and their direction, where
applicable.

Figure 7. Embedded Modem Placement
The evaluation board provides for an embedded modem, the SF56D/SP
SocketModem. The SocketModem is not part of the kit. Tab le 18 on page
29 lists ordering information for the modem. The interface communicates
with the modem serially. LEDs D7-D10 provide information about the
status of the modem’s interface lines. The phone line connection is for the
U.S. only. To connect to a modem outside of the U.S., modifications must
be made to the board. The necessary data is found in the SocketModem
