22.3.2.1
Read: Anytime. In emulation modes, read operations will return the data from the external bus, in all other
modes the data source is depending on the data direction value.
Write: Anytime. In emulation modes, write operations will also be directed to the external bus.
22.3.2.2
Read: Anytime. In emulation modes, read operations will return the data from the external bus, in all other
modes the data source is depending on the data direction value.

Port A — Port A pins 7–0 are associated with address outputs ADDR15 through ADDR8 respectively in
expanded modes. When this port is not used for external addresses, these pins can be used as general purpose
I/O. If the data direction bits of the associated I/O pins are set to logic level “1”, a read returns the value of the
port register, otherwise the buffered pin input state is read.
