Deadtime Prescaler Value
Description
Selects the division factor of the system clock. This prescaled clock is used by the deadtime counter.
This field is write protected. It can be written only when MODE[WPDIS] = 1.
0x Divide the system clock by 1.
10 Divide the system clock by 4.
11 Divide the system clock by 16.
Deadtime Value
Selects the deadtime insertion value for the deadtime counter. The deadtime counter is clocked by a
scaled version of the system clock. See the description of DTPS.
Deadtime insert value = (DTPS × DTVAL).
DTVAL selects the number of deadtime counts inserted as follows:
When DTVAL is 0, no counts are inserted.
When DTVAL is 1, 1 count is inserted.
When DTVAL is 2, 2 counts are inserted.
This pattern continues up to a possible 63 counts.
This field is write protected. It can be written only when MODE[WPDIS] = 1.
39.3.16 FTM External Trigger (FTMx_EXTTRIG)
This register indicates when a channel trigger was generated, enables the generation of a
trigger when the FTM counter is equal to its initial value, and selects which channels are
used in the generation of the channel triggers. Several channels can be selected to
generate multiple triggers in one PWM period.
Channels 6 and 7 are not used to generate channel triggers.
