OK found the DPLL problem:
The DPLL timer value 2 is not updated until you write timer value 1
(and timer value 4 is not updated until you write timer value 3)

As a workaround, just use timer 1
or setp all the timers in order at the start

( I could not duplicate the error because I used timer 1 )

It will get fixed,

I never noticed because all of our test files either just used timer 1
or if multiple timers were used, all 4 timers were initialized, order is not even important
its just that if you never setp timer1 to some value initially you can never change timer 2
the same goes for timer 3 and 4, very weird bug
