Store output data for a pin that functions as a general
output port.
If the port D is read while PDDDR bits are set to 1, the
PDDR value is read. If the port D is read while PDDDR
bits are cleared to 0, the pin states are read.
Note: After accessing EXMDLSTP or the RTC register
Description
Description
(address range: H'FFFF40 to H'FFFF5F), you
must perform a dummy read to the external
address space (such as H'FFEF00 to H'FF7FF)
outside the range H'FFFF40 to H'FFFF5F before
reading PORTD.
