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

Bit 0 ~ Bit 7 (MR0 ~ MR7) : Multiplication result data
The multiplier can make a multiplication with X*Y. The multiplicator data buffer X is ACC(acculator) and
the multiplicand data buffer Y is RB PAGE2. The LSB 8-bit of maximum 24 bit multiplication result MR
will be stored in RC PAGE2.
RC PAGE2 = MR(0~7) = LSB 8-bit (X*Y)
