Section 15 Serial Communication Interface (SCI, IrDA)
15.3.11 Serial Extension Mode Register (SEMR)
SEMR selects the clock source in asynchronous mode for the SCI_2. The basic clock can be
automatically set by selecting the average transfer rate.

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
Reserved
If these bits are read, an undefined value will be
returned and cannot be modified.
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
change
output
16 times the transfer rate.
