Chapter 39 FlexTimer (FTM)
• Each pair of channels can be combined to generate a PWM signal (with independent
control of both edges of PWM signal)
• The FTM channels can operate as pairs with equal outputs, pairs with
complementary outputs, or independent channels (with independent outputs)
• The deadtime insertion is available for each complementary pair
• Generation of triggers (match trigger)
• Software control of PWM outputs
• Up to 4 fault inputs for global fault control
• The polarity of each channel is configurable
• The generation of an interrupt per channel
• The generation of an interrupt when the counter overflows
• The generation of an interrupt when the fault condition is detected
• Synchronized loading of write buffered FTM registers
• Write protection for critical registers
• Backwards compatible with TPM
• Testing of input captures for a stuck at zero and one conditions
• Dual edge capture for pulse and period width measurement
• Quadrature decoder with input filters, relative position counting and interrupt on
position count or capture of position count on external event
39.1.3 Modes of Operation
When the MCU is in an active BDM mode, the FTM temporarily suspends all counting
until the MCU returns to normal user operating mode. During stop mode, all FTM input
clocks are stopped, so the FTM is effectively disabled until clocks resume. During wait
mode, the FTM continues to operate normally. If the FTM does not need to produce a
real time reference or provide the interrupt sources needed to wake the MCU from wait
mode, the power can then be saved by disabling FTM functions before entering wait
mode.
