The duty I/O register is an 8-bit register that confirms and determines the operating status of the
CTL circuit.
It is initialized to H'F1 by a reset, and in standby mode, module stop mode, and CTL stop mode.
Bits 7, 6, and 5: VISS Interrupt Setting Bits (VCTR2, VCTR1, VCTR0)
Combination of VCTR2, VCTR1 and VCTR0 sets number of 1 pulse detection in VISS
detection mode. Detecting the set number of pulse detection is considered as VISS detection,
and an interrupt request is generated.
Note:
When changing the detection pulse number during VISS detection, initialize VISS first,
then resume the VISS detection setting.
