Section 18 I/O Ports
18.2.3
Port control register B (PCTRB) is a 32-bit readable/writable register that controls the input/output
direction and pull-up for each bit in the 4-bit port (port 19 pin to port 16 pin). As the initial value
of port data register B (PDTRB) is undefined, each bit in the 4-bit port should be set to output with
PCTRB after writing a value to the PDTRB register.
PCTRB is initialized to H'00000000 by a power-on reset. It is not initialized by a manual reset or
in standby mode, and retains its contents.
