Port E IO register H (PEIORH) is a 16-bit readable/writable register that selects the input/output
direction of pins in port E. Bits PE23IOR to PE16IOR correspond to pins PE23/IRQ7/PWOB to
PE16/IRQ0/SCK1/AH. PEIORH is enabled when port E pins function as general input/output pins
(PE23 to PE16) or as SCI SCK pins, or when PE20 functions as the MMT PCIO pin, and disabled
otherwise.
When port E pins function as PE23 to PE16 or as SCI SCK pins, or when PE20 functions as the
MMT PCIO pin, a pin becomes an output when the corresponding bit in PEIORH is set to 1, and
an input when the bit is cleared to 0.
PEIORH is initialized to H'0000 by an external power-on reset, but is not initialized by a WDT
reset, in standby mode, or in sleep mode.
