Bit 2n + 1 (n = 0–3)—Port Pull-Up Control (PBnPUP): Specifies whether each bit in the 4-bit
port is to be pulled up with a built-in resistor. Pull-up is automatically turned off for a port pin set
to output by bit PBnIO.

Port data register B (PDTRB) is a 16-bit readable/writable register used as a data latch for each bit
in the 4-bit port. When a bit is set as an output, the value written to the PDTRB register is output
from the external pin. When a value is read from the PDTRB register while a bit is set as an input,
the external pin value sampled on the external bus clock is read. When a bit is set as an output, the
value written to the PDTRB register is read.
PDTRB is not initialized by a power-on or manual reset, or in standby mode, and retains its
contents.
