Section 8 I/O Ports
Port 7 Input Data Register (P7PIN)
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.
8.8.3
Port 7 pins also function as the A/D converter analog input pins (AN0 to AN7) and D/A converter
analog output pins (DA0, DA1).
