*)Dummy Bit
Note) All registers except address(000 - 011), Bit5(D5) can be read/write.
Note) Please write “all 0’s” for address(000 - 100), Bit7,6(D7,D6) and address(101), Bit7,6,5,4(D7 - D4)
for normal operation.
Note) Address(000 - 011),Bit5(D5) can not be write and “0” data will be output when it is accessed to read.
INITIALIZATION OF REGISTERS
The registers are initialized at POWER ON RESET only.
Power on reset may not be excuted due to the difference of power up time constant. Thus it is highly recommended
that all the register (address(000 – 101) ) are to be written at the time of the power up and after the abnormal circumstances
happens such as micro interrupt of the power line or mal operation due to lightning.
