8.6.9 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 8.5 summarizes the input pull-up MOS
states.

8.7 Port 7
Port 7 is an 8-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. Port 7 has the following register.
• Port 7 input data register (P7PIN)
8.7.1 Port 7 Input Data Register (P7PIN)
P7PIN indicates the pin states.
Bit Bit Name Initial Value R/W Description
7
P77PIN
Undefined* R
When a P7PIN read is performed, the pin states are

P76PIN
Undefined* R
always read. This register is assigned to the same
address as that of PBDDR. When the register is
5
P75PIN
Undefined* R
programmed, data is programmed in the PBDDR and

P74PIN
Undefined* R
the setting of port B is changed.
