Functional Description
Interrupt
Signal
The eZ80F91 device contains a UART to an infrared encoder/decoder (endec). The endec
is integrated with the on-chip UART0 to allow easy communication between the CPU and
IrDA Physical Layer Specification Version 1.4-compatible infrared transceivers, as dis-
played in
cost, point-to-point communication between PCs, PDAs, mobile telephones, printers, and
other infrared-enabled devices.
When the endec is enabled, the transmit data from the on-chip UART is encoded as digital
signals in accordance with the IrDA standard and output to the infrared transceiver. Like-
wise, data received from the infrared transceiver is decoded by the endec and passed to the
UART. Communication is half-duplex, meaning that simultaneous data transmission and
reception is not allowed.
The baud rate is set by the UART Baud Rate Generator (BRG), which supports IrDA stan-
dard baud rates from 9600 bps to 115.2 kbps. Higher baud rates are possible, but do not meet
