The FlexTimer trigger outputs are also usually used as trigger source by other modules,
for example, the above diagram shows a case of triggering PDB and ADC. See "Chip-
specific Information" in PDB chapter and
ADC Trigger Sources in ADC chapter for
details.
39.1.3.3 FTM Input Capture Options
The following channel 0 input capture source options are selected via SIM_FTMOPT1.
The external pin option is selected by default.
• FTM1 channel 0 input capture = FTM1_CH0 pin or CMP0 output or CMP1 output
• FTM2 channel 0 input capture = FTM2_CH0 pin or CMP0 output or CMP1 output
• FTM2 channel 1 input capture = FTM2_CH1 pin or exclusive OR of FTM2_CH0,
FTM2_CH1, and FTM1_CH1. See FTM Hall sensor support .
39.2 Introduction
NOTE
The number of channels supported can vary for each instance of
the FTM module on a chip. See the chip-specific FTM
information to see how many channels are supported for each
module instance. For example, if a module instance supports
only six channels, references to channel numbers 6 and 7 do not
apply for that instance.
The FlexTimer module (FTM) is a two-to-eight channel timer that supports input capture,
output compare, and the generation of PWM signals to control electric motor and power
management applications. The FTM time reference is a 16-bit counter that can be used as
an unsigned or signed counter.
39.2.1 FlexTimer philosophy
The FlexTimer is built upon a simple timer, the Timer PWM Module – TPM, used for
many years on our HCS08 family of 8-bit microcontrollers. The FlexTimer extends the
functionality to meet the demands of motor control, digital lighting solutions, and power
conversion, while providing low cost and backwards compatibility with the TPM module.
Several key enhancements are made:
• Signed up counter
