13.11.5 CTM9 Double Edge Single Output Pulse Generation
MC68F375
REFERENCE MANUAL
value when the output is to change. The software thus writes the compare value into
register A. In the SASM control register, the software establishes whether the output
flip-flop is to toggle to the opposite state, or is to go to a high or a low level. The output
compare interrupt is typically used to notify the software that the previous compare is
complete and the SASM is available for a new compare value in register A.
Software can initialize the CTM9 to generate both the rising and the falling edge of an
output pulse. With a DASM, pulses as narrow as 0.119 microseconds can be gener-
ated since software action is not needed between the edges. Pulses as long as 3
seconds can be generated. When an interrupt is desired, it can be selected to occur
on every edge or only after the second edge.

both edges of a single output pulse. The software puts the compare value for one edge
in register A and the other one in register B2. The DASM automatically creates both
edges, and the pulse can be selected by software to be a high-going or a low-going.
After the trailing edge, the DASM stops to await further commands from the software.
Note that a single edge output can be generated by writing to only one register.
