7.8 Port 7
7.8.1 Overview
Port 7 is an 8-bit input port that also provides the analog input pins for the A/D converter and
analog output pins for the D/A converter. The pin functions are the same in all modes. Figure 7.15
shows the pin configuration of port 7.

7.8.2 Register Configuration and Descriptions
Table 7.15 summarizes the port 7 registers. Port 7 is an input port, so there is no data direction
register.
