8.8.1
Port 7 is an 8-bit input port. Port 7 pins also function as the A/D converter analog input pins (AN0
to AN7) and D/A converter analog output pins (DA0, DA1). Port 7 functions are the same in all
operating modes.
Figure 8.15 shows the port 7 pin configuration.
8.8.2
Table 8.17 shows the port 7 register configuration. Port 7 is an input-only port, and does not have
a data direction register or data register.
