18.3.3 Port B Control Registers (PBCR, PBCR2)
The port B control registers (PBCR and PBCR2) are 16-bit read/write registers that select the
functions of the 16 multiplex pins in port B. PBCR selects the functions of the pins for the upper 8
bits in port B, and PBCR2 selects the functions of the pins for the lower 8 bits in port B.
PBCR and PBCR2 are initialized to H'0000 by a power-on reset. They are not initialized by a
manual reset or in standby mode or sleep mode.
