set when the TPM counter is counting down, and the channel value register matches the TPM counter. If
ELSnA is set, the corresponding TPMxCHn pin is set when the TPM counter is counting up and the
channel value register matches the TPM counter; and it is cleared when the TPM counter is counting down
and the channel value register matches the TPM counter.
