Fig. 8.2.6 Relationship between port P7 direction register and A-D converter’s input pins
8.2.5 Port P7 direction register
The A-D converter and port P7 use the same pins in common. When using these pins as the A-D converter’s
input pins, set the corresponding bits of the port P7 direction register to “0” to set these ports for the input
mode. Figure 8.2.6 shows the relationship between the port P7 direction register and A-D converter’s input
pins.
