AT91RM3400
Waveform operating mode is entered by setting the WAVE parameter in TC_CMR (Channel
Mode Register).
In Waveform Operating Mode the TC channel generates 1 or 2 PWM signals with the same
frequency and independently programmable duty cycles, or generates different types of one-
shot or repetitive pulses.
In this mode, TIOA is configured as an output and TIOB is defined as an output if it is not used
as an external event (EEVT parameter in TC_CMR).
Figure 142 shows the configuration of the TC channel when programmed in Waveform Oper-
ating Mode.
Depending on the WAVSEL parameter in TC_CMR (Channel Mode Register), the behavior of
TC_CV varies.
With any selection, RA, RB and RC can all be used as compare registers.
RA Compare is used to control the TIOA output, RB Compare is used to control the TIOB out-
put (if correctly configured) and RC Compare is used to control TIOA and/or TIOB outputs.
