Bit 2(P62S) : Select normal I/O PORT62 pin or channel 3 input AD3 pin of ADC
0
P62 (I/O PORT62) pin is selected
1
AD3 (Channel 3 input of ADC) pin is selected
Bit 3(P63S) : Select normal I/O PORT63 pin or channel 4 input AD4 pin of ADC
0
P63 (I/O PORT63) pin is selected
1
AD4 (Channel 4 input of ADC) pin is selected
Bit 4(P64S) : Select normal I/O PORT64 pin or channel 5 input AD5 pin of ADC
0
P64 (I/O PORT64) pin is selected
1
AD5 (Channel 5 input of ADC) pin is selected
Bit 4(P65S) : Select normal I/O PORT65 pin or channel 6 input AD6 pin of ADC
0
P65 (I/O PORT65) pin is selected
1
AD6 (Channel 6 input of ADC) pin is selected
Bit 6(P66S) : Select normal I/O PORT66 pin or external reference voltage input of ADC
0
P66 (I/O PORT66) pin is selected and ADC reference voltage come from internal VDD
1
VREF (External reference voltage input of ADC) pin is selected
This bit can switch AD converter reference voltage coming from internal or external voltage.
If this bit set to internal, then the reference voltage will be VDD and PORT66 is a normal I/O PORT. If it
set to external reference voltage, then the voltage will connected to VREF pin.
