27.2.3 Port B I/O Register H (PBIORH)
PBIORH is a 16-bit readable/writable register that is used to set the pins on port B as inputs or
outputs. The PB18IOR to PB16IOR bits correspond to the PB18 to PB16 pins, respectively. The
setting of PBIORH is valid for the pins for which general I/O function is selected and has no effect
on the pins for which other function is selected. If a bit in PBIORH is set to 1, the corresponding
pin on port B functions as output. If it is cleared to 0, the corresponding pin functions as input.
Bits 15 to 3 in PBIORH are reserved. These bits are always read as 0. The write value should
always be 0.
