Signal
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.
Figure 16 displays the architecture of the infrared endec.
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.
