Port E I/O Register (PEIOR)

PEIOR is a 16-bit readable/writable register that selects the input/output direction of the port E
pins.
The PE15IOR to PE0IOR bits correspond to the PE15/TIOC0A to PE0/TIOC4D pins. PEIOR is
valid only when the port E pins function as the TIOC pins of the MTU (other functions).
Otherwise, PEIOR is invalid. When the port E pins function as the TIOC pins of the MTU (other
functions), setting a bit in PEIOR to 1 sets the pin to output and setting a bit in PEIOR to 0 sets
the pin to input. PEIOR is initialized to H'0000 by a power-on reset, and it is not initialized by a
manual reset, in standby mode, or in sleep mode.

MTU (other functions):
0 R/W
PEnIOR (n = 0 to 15) controls the input/output direction
0 R/W
of the pins.
0 R/W
0: MTU input capture input
