Port A IO register H (PAIORH) is a 16-bit readable/writable register that selects the input/output
direction of pins in port A. Bits PA25IOR to PA16IOR correspond to pins PA25/CS5 to
PA16/WRHH/HHBS/TCLKC/TIOC3A. PAIORH is enabled when port A pins function as general
input/output pins (PA25 to PA16) or PA16 functions as a TPU TIOC pin, and disabled otherwise.
When port A pins function as PA25 to PA16, or PA16 functions as a TPU TIOC pin, a pin
becomes an output when the corresponding bit in PAIORH is set to 1, and an input when the bit is
cleared to 0.
PAIORH 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.
