Bit 2n + 1 (n = 0–7): Port Pull-Up Control (PBnPUP): Controls the pull-up of each bit in the 8-bit
port by means of built-in resistors. This setting is valid even if the port pin is set to output by the
PBnIO bit. Therefore, to avoid unnecessary power consumption and ensure the reliability of the
chip, a pull-up setting should not be made when the corresponding port pin has been set to output.

Bit 2n (n = 0–7)—Port I/O Control (PBnDIR): Controls whether each bit of 8-bit port is an input
or an output.

15.2.2
The port data register (PDTR) is an 8-bit read/write register used as data latches for each bit of the
8-bit port. When a bit is set to be used as an output, the value written into PDTR is output from the
external pin. When a value is read from PDTR, the external pin value sampled on the external bus
clock is returned.
PDTR is not initialized by a power-on reset or manual reset, or in standby mode, and it retains its
contents. However, if PDTR is read when a bus release request is issued (when BREQ is asserted),
its value may not be read correctly. Therefore, BREQ should not be asserted when reading PDTR.
