30.2.4 Port B I/O Register L (PBIORL)
PBIORL is a 16-bit readable/writable register that is used to set the pins on port B as inputs or
outputs. The PB15IOR to PB0IOR bits correspond to the PB15 to PB0 pins, respectively. The
setting of PBIORL 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 PBIORL 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.

30.2.5 Port B Control Registers H1, H2, L1 to L4 (PBCRH1, PBCRH2, PBCRL1 to
PBCRL4)
PBCRH1, PBCRH2, and PBCRL1 to PBCRL4 are 16-bit readable/writable registers that are used
to select the function of the multiplexed pins on port B. See table 30.2 for the multiplexed
functions.

Notes: 1. Not initialized by a reset triggered by WDT overflow.
2. To write to PBCRH2, write by 16-bit or 32-bit access such that the write value for bits 15
to 8 is H'A5 and that for bits 7 to 4 is 0.
