Port B IO register H (PBIORH) is a 16-bit readable/writable register that selects the input/output
direction of pins in port B. Bits PB23IOR to PB16IOR correspond to pins
PB23/CASHH1/TxD1/TEND0 to PB16/CASLL0. PBIORH is enabled when port B pins function
as general input/output pins (PB23 to PB16), and disabled otherwise.
When port B pins function as PB23 to PB16, a pin becomes an output when the corresponding bit
in PBIORH is set to 1, and an input when the bit is cleared to 0.
PBIORH 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.
