20.1.3
PBIORL is a 16-bit readable/writable register that is used to set the pins on port B as inputs or
outputs. Bits PB7IOR to PB0IOR correspond to pins PB7 to PB0, respectively (names of
multiplexed pins are here given as port names and pin numbers alone). PBIORL is enabled when
the port B pins are functioning as general-purpose inputs/outputs (PB7 to PB0). In other states,
PBIORL is disabled.
A given pin on port B will be an output pin if the corresponding bit in PBIORL is set to 1, and an
input pin if the bit is cleared to 0.
However, bits 1 and 0 of PBIORL are disabled in SH7136.
Bits 15 to 8 of PBIORL are reserved. These bits are always read as 0. The write value should
always be 0.
The initial value of PBIORL is H'0000.

PBCRL1 and PBCRL2 are 16-bit readable/writable registers that are used to select the function of
the multiplexed pins on port B.
