Bit 1 ~ Bit 2 (PC1 ~ PC2): PORTC1,PORTC2 I/O data register
User can use IOC register to define input or output each bit.

Bit 0 ~ Bit 7 (CN10 ~ CN17) : Counter1's buffer that user can read and write.
Counter1 is a 8-bit up-counter with 8-bit prescaler that user can use RC PAGE1 to preset and read the
counter.(write
preset) After a interruption , it will reload the preset value.
Example for writing :
MOV 0x0C, A ; write the data at accumulator to counter1 (preset)
Example for reading :
MOV A, 0x0C ; read the data at counter1 to accumulator
PAGE2,3 (undefined) not allowed to use.
