Bit Bit Name Description
0 WRST Watchdog Timer Reset
Indicates whether a reset caused by the
watchdog timer is generated. This bit is not
cleared by a reset caused by the watchdog
timer.
[Setting condition]
When TCWD overflows and an internal reset
signal is generated

Bit Bit Name Description
3 ABCS Asynchronous Mode Basic Clock Select
Selects the basic clock for one-bit interval in
asynchronous mode. The ABCS setting is
enabled in asynchronous mode (COM = 0 in
SMR3)
0: Basic clock with a frequency 16 times the
transfer rate
1: Basic clock with a frequency 8 times the
transfer rate
Clear this bit to 0 when the IrDA function is
enabled.

According to the standard, the high-level pulse width is
defined to be 1.41 µs at minimum and (3/16 + 2.5%) x bit rate or
(3/16 x bit rate) + 1.08 µs at maximum. For example, when the
frequency of system clock φ is 10 MHz, being equal to or greater
than 1.41 µs, the high-level pulse width at minimum can be
specified as 1.6 µs.
17.7.2 Reception 403 Modified
If a pulse has a high-level width of less than 1.41 µs, the
minimum width allowed, the pulse is not recognized.
