Port C IO register H (PCIORH) is a 16-bit readable/writable register that selects the input/output
direction of pins in port C. Bits PC25IOR to PC16IOR correspond to pins
PC25/A25/TIOC3B/TCLKD to PC16/A16/TIOC3A. PCIORH is enabled when port C pins
function as general input/output pins (PC25 to PC16) or TPU TIOC pins, and disabled otherwise.
When port C pins function as PC25 to PC16 or TPU TIOC pins, a pin becomes an output when the
corresponding bit in PCIORH is set to 1, and an input when the bit is cleared to 0.
PCIORH 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.
