Section 19 Pin Function Controller (PFC)
19.2.3
PBIOR is a 16-bit readable/writable register that is used to set the pins on port B as inputs or
outputs. Bits PB9IOR, PB5IOR, and PB4IOR correspond to pins PB9/IRQ7/A21/ADTRG,
PB5/IRQ3/POE3/CASL, and PB4/IRQ2/POE2/RASL, respectively. PBIOR is enabled when the
port B pins are functioning as general-purpose inputs/outputs (PB9, PB5, and PB4). In other
states, PBIOR is disabled. A given pin on port B will be an output pin if the corresponding bit in
PBIOR is set to 1, and an input pin if the bit is cleared to 0.
Bits 15 to 10, 8 to 6, and 3 to 0 of PBIOR are reserved. These bits are always read as 0. The write
value should always be 0.
PBIOR is initialized to H'0000 by a power-on reset; however, the register is not initialized by a
manual reset or in sleep mode or software standby mode.

PBCR1 to PBCR3 are 16-bit readable/writable registers that are used to select the function of the
multiplexed pins on port B.
PBCR1 to PBCR3 are initialized to the values shown in table 19.7 by a power-on reset; however,
the registers are not initialized by a manual reset or in sleep mode or software standby mode.
