20.1.7
PEIORL and PEIORH are 16-bit readable/writable registers that are used to set the pins on port E
as inputs or outputs. PE21IOR to PE0IOR correspond to pins PE21 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. PEIORH is enabled
when the port E pins are functioning as general-purpose inputs/outputs (PE21 to PE16), and the
TIOC pin is functioning as inputs/outputs of MTU2S. In other states, PEIORH is disabled.
A given pin on port E will be an output pin if the corresponding bit in PEIORH or PEIORL is set
to 1, and an input pin if the bit is cleared to 0.
Bits 15 to 6 of PEIORH are reserved. These bits are always read as 0. The write value should
always be 0.
The initial values of PEIORL and PEIORH are H'0000, respectively.
