The straight forward way is to program one channel for the input pulse and
one for the output pulse.

The communicate between the two in the interrupt handlers.

If you want to do it entirely within the TPU, find a copy of the TPU
assembler and have at it.

    Good luck, Bob Smith

Subject: [68300] Does anybody have a TPU solution for this?
