ADE0
Bit 7:
This bit must be set to “0” all the time
.
Bit 6 (ADE6):
AD converter enable bit of P55 pin
0
= Disable ADC6, P55 functions as I/O pin
1
= Enable ADC6 to function as analog input pin
Bit 5 (ADE5):
AD converter enable bit of P70 pin
0
= Disable ADC5, P70 functions as I/O pin
1
= Enable ADC5 to function as analog input pin
Bit 4 (ADE4):
AD converter enable bit of P67 pin
0
= Disable ADC4, P67 functions as I/O pin
1
= Enable ADC4 to function as analog input pin
Bit 3 (ADE3):
AD converter enable bit of P53 pin
0
= Disable ADC3, P53 functions as I/O pin
1
= Enable ADC3 to function as analog input pin
Bit 2 (ADE2):
AD converter enable bit of P52 pin
0
= Disable ADC2, P52 functions as I/O pin
1
= Enable ADC2 to function as analog input pin
Bit 1 (ADE1):
AD converter enable bit of P51 pin
0
= Disable ADC1, P51 functions as I/O pin
1
= Enable ADC1 to function as analog input pin
Bit 0 (ADE0):
AD converter enable bit of P50 pin
0
= Disable ADC0, P50 functions as I/O pin
1
= Enable ADC0 to function as analog input pin
