Bit 0 (P90S): Select normal I/O Port90 pin or ADC Channel 1 input AD1 pin

"0" : P90 (I/O Port 90) pin is selected

"1" : AD1 (ADC Channel 1 input) pin is selected

Bit 1 (P91S): Select normal I/O Port 91 pin or Channel 2 input AD2 pin of ADC

"0" : P91 (I/O Port 91) pin is selected

"1" : AD2 (ADC Channel 2 input) pin is selected

Bit 2 (P62S): Select normal I/O Port 62 pin or Channel 3 input AD3 pin of ADC

"0" : P62 (I/O Port 62) pin is selected

"1" : AD3 (ADC Channel 3 input) pin is selected

Bit 3 (P63S): Select normal I/O Port 63 pin or Channel 4 input AD4 pin of ADC

"0" : P63 (I/O Port 63) pin is selected

"1" : AD4 (ADC Channel 4 input) pin is selected

Bit 4 (P64S): Select normal I/O Port 64 pin or Channel 5 input AD5 pin of ADC

"0" : P64 (I/O Port 64) pin is selected

"1" : AD5 (ADC Channel 5 input) pin is selected

Bit 5 (P65S): Select normal I/O Port 65 pin or Channel 6 input AD6 pin of ADC

"0" : P65 (I/O Port 65) pin is selected

"1" : AD5 (ADC Channel 6 input) pin is selected

Bit 6 (undefined): This bit is not used. However, it must be cleared to “0” to prevent

possible error from occuring.

Bit 7 (undefined): This bit is not used

NOTE

1. ADC Channel 1 and Channel 2 are shared with Port 90 and Port 91.

2. ADC Channel 3 and Channel 6 are shared with Port 62 and Port 65.
