Infrared Encoder/Decoder

Z8 Encore! XP F082A Series products contain a fully-functional, high-performance

UART to Infrared Encoder/Decoder (endec). The infrared endec is integrated with an on-

chip UART to allow easy communication between the Z8 Encore! XP MCU and IrDA

Physical Layer Specification, Version 1.3-compliant infrared transceivers. Infrared com-

munication provides secure, reliable, low-cost, point-to-point communication between

PCs, PDAs, cell phones, printers and other infrared enabled devices.

Architecture

Figure 16 displays the architecture of the infrared endec.

Operation

When the infrared endec is enabled, the transmit data from the associated on-chip UART

is encoded as digital signals in accordance with the IrDA standard and output to the infra-

red transceiver through the TXD pin. Likewise, data received from the infrared transceiver

is passed to the infrared endec through the RXD pin, decoded by the infrared endec and

passed to the UART. Communication is half-duplex, which means simultaneous data

transmission and reception is not allowed.
