Information

• FTM1 FAULT0 = FTM1_FLT0 pin or CMP0 output
• FTM1 FAULT1 = CMP1 output
3.8.2.6 FTM Hardware Triggers
The FTM synchronization hardware triggers are connected in the chip as follows:
• FTM0 hardware trigger 0 = CMP0 Output or FTM1 Match (when enabled in the
FTM1 External Trigger (EXTTRIG) register)
• FTM0 hardware trigger 1 = PDB channel 1 Trigger Output
• FTM0 hardware trigger 2 = FTM0_FLT0 pin
• FTM1 hardware trigger 0 = CMP0 Output
• FTM1 hardware trigger 1 = CMP1 Output
• FTM1 hardware trigger 2 = FTM1_FLT0 pin
For the triggers with more than one option, the SOPT4 register in the SIM module
controls the selection.
3.8.2.7 Input capture options for FTM module instances
The following channel 0 input capture source options are selected via the SOPT4 register
in the SIM module. The external pin option is selected by default.
• FTM1 channel 0 input capture = FTM1_CH0 pin or CMP0 output or CMP1 output
or USB start of frame pulse
NOTE
When the USB start of frame pulse option is selected as an
FTM channel input capture, disable the USB SOF token
interrupt in the USB Interrupt Enable register
(INTEN[SOFTOKEN]) to avoid USB enumeration conflicts.
3.8.2.8 FTM output triggers for other modules
FTM output triggers can be selected as input triggers for the PDB and ADC modules. See
PDB Instantiation and ADC triggers.
