Bit 2(ADRES) : Resolution selection for ADC
Bit 3 : (undefined) not allowed to use
Bit 4 ~ Bit 5(AD8 ~ AD9) : The most significant 2 bit of 10-bit ADC conversion output data
Bit 0 ~ Bit 1 (PWM1[8] ~ PWM1[9]): The Most Significant Byte of PWM1 Duty Cycle
A specified value keeps the PWM1 output to stay at high until the value matches with TMR1.
Bit 2 Bit 7 : unused
Bit 0 ~ Bit 7 (RAM_A0 ~ RAM_A7) : data RAM address
The content of this register is a period (time base) of PWM1. The frequency of PWM1 is the reverse of the
period.
P97
Bit 0 ~ Bit 7 (P90 ~ P97) : 8-bit PORT9(0~7) I/O data register
Bit 0 ~ Bit 7 (RAM_D0 ~ RAM_D7) : Data RAM’s data register.

Combine these two bits and RB PAGE1 as complete 10-bit ADC conversion output data.

The data RAM bank’s selection is from R7 PAGE1 bit0 (RAM_B0).

User can use IOC register to define input or output each bit.

When 8-bit resolution is selected, the most significant(MSB) 8-bit data output of the internal 10-bit ADC
will be mapping to RB PAGE1 so R7 PAGE1 bit 4 ~5 will be of no use.
When 10-bit resolution is selected, 10-bit data output of the internal 10-bit ADC will be exactly mapping
to RB PAGE1 and R7 PAGE1 bit 4 ~5.
ADC is 8-bit resolution
ADC is 10-bit resolution
