Port B Control Registers H1 to H4, L1 to L4 (PBCRH1 to PBCRH4, PBCRL1 to

PBCRL4)

PBCRH1 to PBCRH4 and PBCRL1 to PBCRL4 are 16-bit readable/writable registers that are

used to select the function of the multiplexed pins on port B.

PBCRH1 to PBCRH4 and PBCRL1 to PBCRL4 are initialized to the values shown in table 19.5

by a power-on reset; but are not initialized by a manual reset or in sleep mode or software standby

mode.
