5.8 Port 7
Port 7 is an 8-bit input port that also provides the analog input pins for the A/D converter module.
The pin functions are the same in both the expanded and single-chip modes.
Table 5-14 lists the pin functions. Table 5-15 describes the port 7 data register, which simply
consists of connections of the port 7 pins to the internal data bus. Figure 5-13 shows a schematic
