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 full-
duplex, synchronous, character-oriented channel that supports a four-wire
interface.

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

IrDA Transceiver
The Z8 Encore! contains two fully-functional, high-performance UARTs
with Infrared Encoder/Decoders (Endec). The Infrared Endec is inte-
grated 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.
