Field Description
2
DECAPEN0
Dual Edge Capture Mode Enable For n = 0
Enables the Dual Edge Capture mode in the channels (n) and (n+1). See Channel Modes .
This field is write protected. It can be written only when MODE[WPDIS] = 1.
1
COMP0
Complement Of Channel (n) For n = 0
In Complementary mode the channel (n+1) output is the inverse of the channel (n) output.
This field is write protected. It can be written only when MODE[WPDIS] = 1.
0 The channel (n+1) output is the same as the channel (n) output.
1 The channel (n+1) output is the complement of the channel (n) output.
0
COMBINE0
Combine Channels For n = 0
Used on the selection of the combine mode for channels (n) and (n+1). See Channel Modes .
This field is write protected. It can be written only when MODE[WPDIS] = 1.
41.4.15 Deadtime Configuration (FTMx_DEADTIME)
This register selects the deadtime prescaler and value for all pair of channels.

FTMx_DEADTIME field descriptions
Field Description
31–20
Reserved
This field is reserved.
This read-only field is reserved and always has the value 0.
19–16
DTVALEX
Extended Deadtime Value
This field is a bit extension of the DTVAL field. It defines the 4 most significant bits of the deadtime value.
The maximum deadtime value is extended to 1023 using the concatenation {DTVALEX, DTVAL}.
Deadtime insert value = (DTPS × {DTVALEX, DTVAL}).
This field is write protected. It can be written only when MODE[WPDIS] = 1.
NOTE: If full compatibility is needed with previous software versions, write 0 to DTVALEX bits.
15–8
Reserved
This field is reserved.
This read-only field is reserved and always has the value 0.
7–6
DTPS
Deadtime Prescaler Value
Selects the division factor of the FTM input clock. This prescaled clock is used by the deadtime counter.
