【0xFB : Clear interrupt of PWM continuous flashing】
Name:
CLR_DETECT_PWM_FINISH
Address: 0xFB
Description: DETECT_PWM_FINISH Clear Register. Clears the DETECT_PWM_FINISH by writing „0‟ these registers.
If you write „1‟, the operation is invalid. LED 0-7 has each clear bit.
1 : Invalid. 0 :Clear.

【0xFE : Write register for operation check of CPU】
Name:
WACT
Address: 0xFE
Description: This register is a write register for operational check of the IC. The value written to this register for
operation check is copied to register for operation check (Address is 0x1E). Comparing the write value with
the read value is equal, CPU and I/F are operating normally.
