D.3 Queued Output Match TPU Function (QOM)
MPC555 / MPC556
USER’S MANUAL
QOM can generate single or multiple output match events from a table of offsets in pa-
rameter RAM. Loop modes allow complex pulse trains to be generated once, a spec-
ified number of times, or continuously. The function can be triggered by a link from
another TPU channel. In addition, the reference time for the sequence of matches can
be obtained from another channel. QOM can generate pulse-width modulated wave-
forms, including waveforms with high times of 0% or 100%. QOM also allows a TPU
channel to be used as a discrete output pin. See Motorola TPU Progamming Note
Queued Output Match TPU Function (QOM), (TPUPN01/D).
