Each TPM may be configured for buffered, center-aligned pulse-width modulation (CPWM) on all
channels
Clock sources independently selectable per TPM (multiple TPMs device)
Selectable clock sources (device dependent): bus clock, fixed system clock, external pin
Clock prescaler taps for divide by 1, 2, 4, 8, 16, 32, 64, or 128
16-bit free-running or up/down (CPWM) count operation
16-bit modulus register to control counter range
Timer system enable
One interrupt per channel plus a terminal count interrupt for each TPM module (multiple TPMs
device)
Channel features:
— Each channel may be input capture, output compare, or buffered edge-aligned PWM
— Rising-edge, falling-edge, or any-edge input capture trigger
— Set, clear, or toggle output compare action
— Selectable polarity on PWM outputs
