NOTES:
1. These bits are used when the MCU is in master mode in I
2. These bits are used when the MCU is in slave mode in I
3. The external clock synchronous function can be selected with the combination of the SU1HIM bit and the SCLKDIV bit in the
UiSMR register. The SU1HIM bit is used in GCI mode.
