Description
IrRx Data Invert
Specifies the logic level of the IrRxD output to be
inverted. When inversion is performed, the high
pulse width specified by bits 6 to 4 becomes the
low pulse width.
0: Transmit data is used as IrRxD output without
1: Transmit data is inverted before used as IrRxD
Reserved
These bits are always read as 0 and cannot be
modified.
Description

Asynchronous basic clock selection (valid only in
asynchronous mode)
Selects the basic clock for 1-bit period in
asynchronous mode.
0: Operates on a basic clock with a frequency of
1: Operates on a basic clock with a frequency of 8
