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). This bit reconfigures the function of
MSnA, ELSnB:ELSnA and ELS(n+1)B:ELS(n+1)A bits in dual edge capture mode according to Table
37-7.
This field applies only when FTMEN = 1.
This field is write protected. It can be written only when MODE[WPDIS] = 1.
0 The dual edge capture mode in this pair of channels is disabled.
1 The dual edge capture mode in this pair of channels is enabled.
1
COMP0
Complement of Channel (n) for n = 0
Enables complementary mode for the combined channels. 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
Enables the combine feature for channels (n) and (n+1).
This field is write protected. It can be written only when MODE[WPDIS] = 1.
0 Channels (n) and (n+1) are independent.
1 Channels (n) and (n+1) are combined.
37.3.15 Deadtime Insertion Control (FTMx_DEADTIME)
This register selects the deadtime prescaler factor and deadtime value. All FTM channels
use this clock prescaler and this deadtime value for the deadtime insertion.
Addresses: FTM0_DEADTIME is 4003_8000h base + 68h offset = 4003_8068h
FTM1_DEADTIME is 4003_9000h base + 68h offset = 4003_9068h
FTM2_DEADTIME is 400B_8000h base + 68h offset = 400B_8068h
