Description
UART SIR Low Power Mode
This bit selects the IrDA encoding mode. If this bit is cleared to 0,
low-level bits are transmitted as an active High pulse with a width of
3/16th of the bit period. If this bit is set to 1, low-level bits are transmitted
with a pulse width which is 3 times the period of the IrLPBaud16 input
signal, regardless of the selected bit rate. Setting this bit uses less power,
but might reduce transmission distances. See page 270 for more
information.
UART SIR Enable
If this bit is set to 1, the IrDA SIR block is enabled, and the UART will
transmit and receive data using SIR protocol.
UART Enable
If this bit is set to 1, the UART is enabled. When the UART is disabled
in the middle of transmission or reception, it completes the current
character before stopping.
