【0xF4 : Clear Interrupt of PWM continuous flashing】
Name:
CLR_DETECT_PWM_FINISH
Address: 0xF4
Description: DETECT_PWM_FINISH Clear Register. Clear the DETECT_PWM_FINISH by writing ‘0’ to these registers.
If the written value is ‘1’, the operation is not valid.
1 : Invalid. 0 : Clear.

【0xFC : Control PWM function】
Name:
PWM_CNT
Address: 0xFC
Description: This register is used to control PWM function.
By writing ‘1’ to the register which value is ‘0’, the PWM function is started.
By writing ‘0’ to the register which value is ‘1’, the PWM function is stopped.
In the case that the PWM function is finished by reaching repeat number, set ‘0’ to this register for the next
operation of PWM function.
