8-BIT MICRO-CONTROLLER
IOC6 ~ IOC9
( I/O Port Control Register )
Five I/O direction control registers.
“1” put the relative I/O pin into high impedance, while “0” put the relative I/O pin as output.
User can see IOCB register how to switch to normal I/O port.

Bit0 unused
Bit4~Bit1:”000" to “1001” are ten blocks of RAM area. User can use 2.5K RAM with RC ram address.
Bit 5 unused
Bit6: port8 low nibble switch, 0/1= normal I/O port/SEGMENT output .
Bit7: port8 high nibble switch , 0/1= normal I/O port/SEGMENT output
IOCB
(LCD ADDRESS)
PAGE0 : Bit6 ~ Bit0 = LCDA6 ~ LCDA0
The LCD display data is stored in the data RAM . The relation of data area and COM/SEG pin is as below:
