Port B I/O Registers 0, 1 (PBIOR0, PBIOR1)
PBIOR0 and PBIOR1 are 16-bit readable/writable registers that are used to set the pins on port B
as inputs or outputs. The PB22IOR to PB1IOR bits correspond to the PB22 to PB1 pins,
respectively. PBIOR1 and PBIOR0 are enabled when the port B pins are functioning as general-
purpose I/O (PB22 to PB1) or TIOC I/O of multi-function timer pulse unit 2. In other states, they
are disabled. If a bit in PBIOR1 or PBIOR0 is set to 1, the corresponding pin on port B functions
as output pin. If it is cleared to 0, the corresponding pin functions as an input pin.
