Pausing hardware OC

[dibs]

Posted on April 06, 2015 at 21:06

I have a chain of 3 timers with TIMA -> TIMB -> TIMC.

When TIMB is triggered it creates a pulse on an output pin via OPM. It then triggers TIMC to do an IC on its counter.

What I want to do is to be able to programatically pause (and then reenable) the hardware pulse in TIMB while always still passing the input trigger to TIMC. So far, everything that I have tried ends up somehow changing the pulse length on the TIMB output.

Any ideas?
