15.1.1
PAIORL is a 16-bit readable/writable register that is used to set the pins on port A as inputs or
outputs. Bits PA15IOR to PA0IOR correspond to pins PA15 to PA0 (names of multiplexed pins
are here given as port names and pin numbers alone). PAIORL is enabled when the port A pins are
functioning as general-purpose inputs/outputs (PA15 to PA0). In other states, PAIORL is disabled.
A given pin on port A will be an output pin if the corresponding bit in PAIORL is set to 1, and an
input pin if the bit is cleared to 0.
However, bits 15 to 10, 5, and 2 of PAIORL are disabled in SH7124.
The initial value of PAIORL is H'0000.

15.1.2
PACRL1 to PACRL4 are 16-bit readable/writable registers that are used to select the functions of
the multiplexed pins on port A.
