I2US0WT
This bit is used to release the communication wait state ("L" level output on the I2CU0_SCL
pin) in the slave mode. Writing "1" to this bit during the communication wait state releases the
state ("L" level output of the I2CU0_SCL pin is released).
The I2US0WT bit is a write-only bit and always returns "0" for reading.
0:
Not release the communication wait state (initial value)
1:
Release the communication wait state

Reserved bit
[Note]
Ÿ
Switch the system clock to the high-speed clock when releasing the communication wait status.
