Port 6 Input Pull-Up MOS
Port 6 has a built-in input pull-up MOS that can be controlled by software. This input pull-up
MOS can be used regardless of the operating mode. Table 9.5 summarizes the input pull-up MOS
states.

Port 7
Port 7 is a 6-bit input port. Port 7 pins also function as the A/D converter analog input pins, D/A
converter analog output pins, and interrupt input pins. When the ISS bit in ISSR is set to 1, these
pins can be used as the interrupt input pins. Port 7 has the following register.
