Specifies the physical address of the bus transaction.
Driven by an external bus master when it owns the ex-
ternal bus. Only for testing purposes.
Driven by the MPC555 / MPC556 along with the ad-
dress when it owns the external bus. Driven high indi-
cates that a read access is in progress. Driven low
indicates that a write access is in progress.
Driven by an external master when it owns the exter-
nal bus. Driven high indicates that a read access is in
progress. Driven low indicates that a write access is in
progress.
Driven by the MPC555 / MPC556 along with the ad-
dress when it owns the external bus. Driven low indi-
cates that a burst transfer is in progress. Driven high
indicates that the current transfer is not a burst.
Driven by an external master when it owns the exter-
nal bus. Driven low indicates that a burst transfer is in
progress. Driven high indicates that the current trans-
fer is not a burst. The MPC555 / MPC556 does not
support burst accesses to internal slaves.
Driven by the MPC555 / MPC556 along with the ad-
dress when it owns the external bus. Specifies the
data transfer size for the transaction.
Driven by an external master when it owns the exter-
nal bus. Specifies the data transfer size for the trans-
action.
Driven by the MPC555 / MPC556 along with the ad-
dress when it owns the external bus. Indicates addi-
tional information about the address on the current
transaction.
Only for testing purposes.
