PIC16F630/676
3.2.3
Each PORTA pin is multiplexed with other functions.
The pins and their combined functions are briefly
described here. For specific information about individ-
ual functions such as the comparator or the A/D, refer
to the appropriate section in this Data Sheet.
3.2.3.1
Figure 3-1 shows the diagram for this pin. The RA0 pin
is configurable to function as one of the following:
• a general purpose I/O
• an analog input for the A/D (PIC16F676 only)
• an analog input to the comparator
3.2.3.2
Figure 3-1 shows the diagram for this pin. The RA1 pin
is configurable to function as one of the following:
• as a general purpose I/O
• an analog input for the A/D (PIC16F676 only)
• an analog input to the comparator
• a voltage reference input for the A/D (PIC16F676
