USER’S MANUAL
Refer to TPU programming note Table Stepper Motor (TSM) TPU Function
(TPUPN04/D) for more information.
Any channel of the TPU can capture the value of a specified TCR or any specified lo-
cation in parameter RAM upon the occurrence of each transition or specified number
of transitions, and then generate an interrupt request to notify the CPU32. The times
of the most recent two transitions are maintained in parameter RAM. A channel can
perform input captures continually, or a channel can detect a single transition or spec-
ified number of transitions, ceasing channel activity until reinitialization. After each
transition or specified number of transitions, the channel can generate a link to other
channels.
Refer to TPU programming note New Input Capture/Transition Counter (NITC) TPU
Function (TPUPN08/D) for more information.
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.
Refer to TPU programming note Queued Output Match (QOM) TPU Function
(TPUPN01/D) for more information.
PTA accumulates a 32-bit sum of the total high time, low time, or period of an input
signal over a programmable number of periods or pulses. The accumulation can start
on a rising or falling edge. After the specified number of periods or pulses, PTA
generates an interrupt request and optionally generates links to other channels.
From one to 255 period measurements can be made and summed with the previous
measurement(s) before the TPU interrupts the CPU32, providing instantaneous or
average frequency measurement capability, and the latest complete accumulation
(over the programmed number of periods).
Refer to TPU programming note Programmable Time Accumulator (PTA) TPU Func-
tion (TPUPN06/D) for more information.
MCPWM generates pulse-width modulated outputs with full 0% to 100% duty cycle
range independent of other TPU activity. This capability requires two TPU channels
plus an external gate for one PWM channel. (A simple one-channel PWM capability is
supported by the QOM function.)
