2-state or 3-state access space can be designated for external
expansion areas
Number of program wait states can be set for external expansion areas
Can be activated by internal interrupt or software
Multiple transfers or multiple types of transfer possible for one
activation source
Transfer possible in repeat mode, block transfer mode, etc.
Request can be sent to CPU for interrupt that activated DTC
One 16-bit free-running counter (also usable for external event
counting)
Two output compare outputs
