UART SIR Low-Power Mode
This bit selects the IrDA encoding mode.
DescriptionValue
Low-level bits are transmitted as an active High pulse with a
width of 3/16th of the bit period.
0
The UART operates in SIR Low-Power mode. 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.
1
Setting this bit uses less power, but might reduce transmission distances.
See page 1183 for more information.
