Chip signal name Module signal
name
Description I/O
TPM_CLKIN[1:0] TPM_EXTCLK External clock. TPM external clock can be selected to increment
the TPM counter on every rising edge synchronized to the
counter clock.
I
TPM0_CH[5:0] TPM_CHn 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.
