Section 14 Pin Function Controller (PFC)
14.1.3 Port B IO Register L (PBIORL)
PBIORL is a 16-bit readable/writable register that selects the input/output directions of the port B
pins. Bits PB13IOR to PB0IOR correspond to pins PB13 to PB00 (the pin name abbreviations for
multiplexed functions are omitted). PBIORL is enabled when a port B pin functions as a general
input/output (PB13 to PB00), otherwise, disabled.
Setting a bit in PBIORL to 1 makes the corresponding pin function as an output and clearing a bit
in PBIORL to 0 makes the pin function as an input.
Bits 15 and 14 in PBIORL are reserved. These bits are always read as 0. The write value should
always be 0.
The initial value of PAIBRL is H'0000.
14.1.4 Port B Control Register L1 and L2 (PBCRL1 and PBCRL2)
PBCRL1 and PBCRL2 are 16-bit readable/writable registers that select the pin functions for the
multiplexed port B pins.
