0 = Disable ADC7, P67 acts as I/O pin
1 = Enable ADC7 acts as analog input pin
Bit 6 (ADE6 ): AD converter enable bit of P66 pin
0 = Disable ADC6, P66 acts as I/O pin
1 = Enable ADC6 acts as analog input pin
Bit 5 (ADE5 ): AD converter enable bit of P65 pin
0 = Disable ADC5, P65 acts as I/O pin
1 = Enable ADC5 acts as analog input pin
Bit 4 (ADE4 ): AD converter enable bit of P64 pin
0 = Disable ADC4, P64 acts as I/O pin
1 = Enable ADC4 acts as analog input pin
Bit 3 (ADE3 ): AD converter enable bit of P63 pin
0 = Disable ADC3, P63 acts as I/O pin
1 = Enable ADC3 acts as analog input pin
Bit 2 (ADE2 ): AD converter enable bit of P62 pin
0 = Disable ADC2, P63 acts as I/O pin
1 = Enable ADC2 acts as analog input pin
Bit 1 (ADE1 ): AD converter enable bit of P61 pin
0 = Disable ADC1, P61 acts as I/O pin
