User documentation ================== FTM Operation Modes ------------------- There are 7 FTM modes: - Edge-align PWM(EPWM) mode - Center-align PWM(CPWM) mode - Complimentary mode and dead-time insertion - Combine mode - Single-edge capture mode - Dual-edge capture mode - Quadrature decoder mode Edge-align PWM (EPWM) mode ++++++++++++++++++++++++++ - In the edge-align PWM mode, the FTM counter counts up from the FTM_CNTIN value to the FTM_MOD value. All FTM channels’ signals align at the edge when the FTM counter changes from the MOD value to the CNTIN value. - The edge-align PWM mode is selected when QUADEN = 0, DECAPEN = 0, MCOMBINE = 0, COMBINE = 0, CPWMS = 0 and MSnB = 1. - The edge-align PWM period is determined by MOD – CNTIN + 0x0001 and the pulse width (or the duty cycle) is determined by CnV – CNTIN or MOD – CNTIN – CnV, depending on the control bits ELSnB:ELSnA.
