Section 30 Pin Function Controller (PFC)
30.2.10 Port E I/O Register L (PEIORL)
PEIORL is 16-bit readable/writable register that is used to set the pins on port E as inputs or
outputs. The PE13IOR, PE11IOR, PE9IOR, and PE7IOR to PE0IOR bits correspond to the PE13,
PE11, PE9, and PE7 to PE0 pins respectively. The setting of PEIORL is valid for the pins for
which general I/O function or TIOC I/O function of the MTU2 is selected. PEIORL has no effect
on the pins for which other function is selected. If a bit in PEIORL is set to 1, the corresponding
pin on port E functions as an output pin. If it is cleared to 0, the corresponding pin functions as an
input pin.
Bits 15, 14, 12, 10, and 8 in PEIORL are reserved. These bits are always read as 0. The write
value should always be 0.

30.2.11 Port E Control Registers L1 to L4 (PECRL1 to PECRL4)
PECRL1 to PECRL4 are 16-bit readable/writable registers that are used to select the functions of
the multiplexed pins on port E. See table 30.5 for the multiplexed functions.
