Has anyone successfully used PulseAccum B on PortT of the MC9S12D64?

We use PulseAccum A on PortT7 and it works fine. Now we need to get
PulseAccum B to also work.

We have tried unsuccessfully to get PulseAccum B working. We have
verified that pulses are coming in on PortT. We have verified that
PBEN in the PBCTL register is high, but it never increments. Is there
anything else we need to do to get PulseAccum B to work?

I'll try cross-posting this on the other HC12 groups ih hopes that
someone has actually done it.

Did you set up input capture edge? PortT0 pin, right?

THAT'S IT! THANKS!

There is no indication in the documentation about this that we could
see. But in 20/20 hindsight PulseAccumA has edge logic built in, and
since the PulseAccumB does not, it would use the Edge logic that is
available.

Thanks again, Edward. You are a great resource and an even bigger help.
