29.3 TPM Signal Descriptions
Signal Description
TPM_EXTCLK External clock. TPM external clock can be selected to increment the TPM
counter on every rising edge synchronized to the counter clock.
TPM_CHn TPM channel (n = 5 to 0). A TPM channel pin is configured as output when
configured in an output compare or PWM mode and the TPM counter is
enabled, otherwise the TPM channel pin is an input.
