19.2.1
Notes:
19.2.2
Notes:
After Reset
1. When the MSTIIC bit is set to 1 (standby), any access to the SSU or the I
2. When the MSTTRC bit is set to 1 (standby), any access to the timer RC associated registers (addresses 0120h
After Reset
1. These bits are enabled when the PWM2 bit is set to 1 (timer mode or PWM mode).
2. Set the BFC bit to 0 (general register) in PWM2 mode.
