Compare Register A, B and C
(RA, RB, and RC)

AT91X40 Series
This mode is entered by setting the WAVE parameter in TC_CMR (Channel Mode
Register).
Waveform Operating Mode allows the TC Channel to generate 1 or 2 PWM signals with
the same frequency and independently programmable duty cycles, or to generate differ-
ent types of one-shot or repetitive pulses.
In this mode, TIOA is configured as output and TIOB is defined as output if it is not used
as an external event (EEVT parameter in TC_CMR).
Figure 47 shows the configuration of the TC Channel when programmed in Waveform
Operating Mode.
In Waveform Operating Mode, RA, RB and RC are all used as compare registers.
RA Compare is used to control the TIOA output. RB Compare is used to control the
TIOB (if configured as output). RC Compare can be programmed to control TIOA and/or
TIOB outputs.
RC Compare can also stop the counter clock (CPCSTOP = 1 in TC_CMR) and/or dis-
able the counter clock (CPCDIS = 1 in TC_CMR).
As in Capture Mode, RC Compare can also generate a trigger if CPCTRG = 1. A trigger
resets the counter so RC can control the period of PWM waveforms.
External Event/Trigger Conditions
An external event can be programmed to be detected on one of the clock sources (XC0,
XC1, XC2) or TIOB. The external event selected can then be used as a trigger.
The parameter EEVT in TC_CMR selects the external trigger. The parameter EEVT-
EDG defines the trigger edge for each of the possible external triggers (rising, falling or
both). If EEVTEDG is cleared (none), no external event is defined.
If TIOB is defined as an external event signal (EEVT = 0), TIOB is no longer used as
output and the TC channel can only generate a waveform on TIOA.
When an external event is defined, it can be used as a trigger by setting bit ENETRG in
TC_CMR.
As in Capture Mode, the SYNC signal, the software trigger and the RC compare trigger
are also available as triggers.
