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
6 P76PIN Undefined* R
5 P75PIN Undefined* R
4 P74PIN Undefined* R
3 P73PIN Undefined* R
2 P72PIN Undefined* R
1 P71PIN Undefined* R
0 P70PIN Undefined* R
When a P7PIN read is performed, the pin states are
always read. This register is assigned to the same
address as that of PBDDR. When the register is
programmed, data is programmed in the PBDDR and
the setting of port B is changed.
Note: The initial value is determined in accordance with the pin states of P77 to P70.
