Pin Function
P77/AN7/DA1
The pin function is switched as shown below according to the combination of the DAE bit in
DACR of the D/A converter and the DAOE1 bit.
P76/AN6/DA0
The pin function is switched as shown below according to the combination of the DAE bit in
DACR of the D/A converter and the DAOE0 bit.
* Determined by the pin states of P77 to P70.
* This pin can always be used as the AN7 input pin.
* This pin can always be used as the AN6 input pin.

When a P7PIN read is performed, the pin states
are always read. P7PIN has the same address as
PBDDR; if a write is performed, data will be
written into PBDDR and the port B setting will be
changed.
