Chapter 22 DP512 Port Integration Module (S12XDP512PIMV2)
22.3.2.5
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.
22.3.2.6
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.

Port C — Port C pins 7–0 are associated with data I/O lines DATA15 through DATA8 respectively in expanded
modes. When this port is not used for external data, 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.
PD7
Port D — Port D pins 7–0 are associated with data I/O lines DATA7 through DATA0 respectively in expanded
modes. When this port is not used for external data, 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.
