Section 19 Pin Function Controller (PFC)
19.2.9 Port E I/O Registers H, L (PEIORH, PEIORL)
PEIORH and PEIORL are 16-bit readable/writable registers that are used to set the pins on port E
as inputs or outputs. PE16IOR to PE0IOR correspond to pins PE16/CS8 to PE0/TIOC0A/DREQ0.
PEIORH and PEIORL are enabled when the port E pins are functioning as general-purpose
inputs/outputs (PE16 to PE0) or the TIOC pin is functioning as inputs/outputs of MTU2. In other
states, they are 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 1 of PEIORH are reserved. These bits are always read as 0. The write value should
always be 0.
PEIORH and PEIORL are initialized to H'0000 by a power-on reset; however, the registers are not
initialized by a manual reset or in sleep mode or software standby mode.
