Port A Data Direction Register (PADDR)
PADDR is an 8-bit write-only register, the individual bits of which specify input or output for the
pins of port A. PADDR cannot be read; if it is, an undefined value will be read.
PADDR is initialized to H'00 by a reset, and in hardware standby mode. It retains its prior state in
software standby mode. The OPE bit in SBYCR is used to select whether the address output pins
retain their output state or become high-impedance when a transition is made to software standby
mode.
