15.1.5
PEIORL is a 16-bit readable/writable register that is used to set the pins on port E as inputs or
outputs. PE15IOR to PE0IOR correspond to pins PE15 to PE0 (names of multiplexed pins are
here given as port names and pin numbers alone). PEIORL is enabled when the port E pins are
functioning as general-purpose inputs/outputs (PE15 to PE0), and the TIOC pin is functioning as
inputs/outputs of MTU2. In other states, PEIORL is disabled.
A given pin on port E will be an output pin if the corresponding bit in PEIORL is set to 1, and an
input pin if the bit is cleared to 0.
However, bits 7 to 4 of PEIORL are disabled in SH7124.
The initial value of PEIORL is H'0000.
