0x1D : Interrupt of PWM continuous flashing】
Name:
DETECT_PWM_FINISH
Address:
0x1D
Description:
This register indicates the end of the LED PWM drive. This register has a bit aware of each LED. The
logical OR of all bits of this register will be the bit PWM that is included the "Interrupt Source" registers.
1 : Finished LED PWM drive. 0 : Clear.

0x1E : Read register for operation check of CPU】
Name:
RACT
Address:
0x1E
Description:
This register is a read register for operational check of the IC. The value written to the write register for
operation check (Address is 0xFE) is copied to this register. Comparing the write value with the read value
is equal, CPU and I/F are operating normally.
The required time to copy to this register from the write register for operation check:About 20usec.

0x85 , 0x8A : Software Reset】
Name:
SRST
Address:
0x85, 0x8A
Description:
These registers make a hardware reset. When the value of "0x85" Register is set to 0x55 and the value of
"0x8A" Register is set to 0xAA, a hardware reset will be generated.
