12.7 Special Conditions
This section deals with actions associated with changing Ir operating modes.
12.7.1 Early Termination of Transmission
Clearing IrCon.TXE (transmit enable bit) stops any transmission in progress and clears all data
within the FIFO, transmit buffer and serial output shifter.
12.7.2 Early Termination of Reception
Clearing IrCon.RXE receive enable bit stops reception immediately. All data within the receive
buffer, serial input shifter and FIFO is cleared.
12.7.3 Changing IrDA Mode
Poll FD or MD bit in IrEnable register until end of transmission is indicated.The new mode can
then be set as described in 12.4 General Configuration.
12.7.4 Loopback Mode
For test purposes, data will be looped back from the output of the transmit serial shifter into the
input of the receive serial shifter when IrEnable.LBM is set.
