Port A I/O Register H (PAIORH)

The port A I/O register H (PAIORH) is a 16-bit read/write register that selects input or output for

the most significant 8 pins of port A. Bits PA23IOR–PA16IOR correspond to pins PA23/

WRHH–

PA16/

AH. PAIORH is enabled when the port A pins function as general input/outputs (PA23–

PA16). For other functions, it is disabled.

For port A pin functions PA23–PA16, a given pin in port A is an output pin if its corresponding

PAIORH bit is set to 1, and an input pin if the bit is cleared to 0.

PAIORH is initialized to H'0000 by external power-on reset; however, it is not initialized for

manual resets, reset by WDT, standby mode, or sleep mode, so the previous data is maintained.

The settings for this register are effective only for the 144-pin version. There are no corresponding

pins for this register in the 112-pin and 120-pin versions. However, read/writes are possible.
