8.4 Port 7
8.4.1 Overview
Port 7 is an 8-bit input-only port that is also used for analog input to the A/D converter and analog
output from the D/A converter. The pin functions are the same in all operating modes. Figure 8.3
shows the pin configuration of port 7.
See section 15, A/D Converter, for details of the A/D converter analog input pins, and section 16,
D/A Converter, for details of the D/A converter analog output pins.
