8.7.5
Port 6 has an on-chip input pull-up MOS function that can be controlled by software. This input
pull-up MOS function can be specified as on or off on a bit-by-bit basis.
The input pull-up MOS current specification can be changed by means of the P6PUE bit. When a
pin is designated as an on-chip peripheral module output pin, the input pull-up MOS is always off.
Table 8.5 summarizes the input pull-up MOS states.
Table 8.5
Legend:
Off:
On/Off: On when the pin is in the input state, P6DDR = 0, and KMPCR = 1; otherwise off.

Port 7 is an 8-bit input only port. Port 7 pins also function as the A/D converter analog input pins
and D/A converter analog output pins. Port 7 functions are the same in all operating modes. Port 7
has the following register.
