PIC16F1619 Timer2 HLT

Hello!
Is it possible to tie the output "TMRx_postscaled" from Timer2 to an external pin without using a logic cell. Logic cells are used for other purposes.

Don't think so.
Obviously with a lot of overhead, you could just generate a pulse in a
routine using TMR2IF, but there doesn't seem to be any way to output
this signal, except using the CLC.

Thanks. I had the idea to try to use PWM3 or CCP in PWM mode for this purpose in a duty cycle close to 1, but here need to experiment, since it is not completely clear how PWM will perceive a single pulse mode.

Yes, A PWM, was a thought I had, but of course the minimum count
would be two, so half the frequency of this clock.
