Functional Description
The FTM is able to generate multiple triggers in one PWM period. Since each trigger is
generated for a specific channel, several channels are required to implement this
functionality. This behavior is described in the following figure.
MOD
FTM counter = C5V
FTM counter = C4V
FTM counter = C3V
FTM counter = C2V
FTM counter = C1V
FTM counter = C0V

(a) CH0TRIG = 0, CH1TRIG = 0, CH2TRIG = 0, CH3TRIG = 0, CH4TRIG = 0, CH5TRIG = 0
(b) CH0TRIG = 1, CH1TRIG = 0, CH2TRIG = 0, CH3TRIG = 0, CH4TRIG = 0, CH5TRIG = 0
(c) CH0TRIG = 0, CH1TRIG = 0, CH2TRIG = 0, CH3TRIG = 1, CH4TRIG = 1, CH5TRIG = 1
(d) CH0TRIG = 1, CH1TRIG = 1, CH2TRIG = 1, CH3TRIG = 1, CH4TRIG = 1, CH5TRIG = 1
Figure 39-238. Channel Match Trigger
Note
It is expected that the channel match trigger be used only in
combine mode.
39.4.21 Initialization Trigger
If INITTRIGEN = 1, then the FTM generates a trigger when the FTM counter is updated
with the CNTIN register value in the following cases.
• The FTM counter is automatically updated with the CNTIN register value by the
selected counting mode.
