Section 8 I/O Ports
Port B Output Data Register (PBODR)
PBODR is an 8-bit readable/writable register that stores output data for the port B pins (PB7 to
PB0). PBODR can always be read or written to, regardless of the contents of PBDDR.
PBODR is initialized to H'00 by a reset and in hardware standby mode. It retains its prior state in
software standby mode.
Port B Input Data Register (PBPIN)
Note:
Reading PBPIN always returns the pin states.
PBPIN has the same address as P8DDR. If a write is performed, data will be written to P8DDR
and the port 8 settings will change.

A port B pin becomes an output port if the corresponding PBDDR bit is set to 1, and an input
port if the bit is cleared to 0.
* Determined by the state of pins PB7 to PB0.
