Tick Period & not disabling a interrupt

Question asked by srikar vadlamani on Mar 3, 2011

Can the value of 1 tick = 5msec, changed, i.e. increase or decrease its value?


Also is there a way in MQX, where no one can disable a particular interrupt, because I have a periodic PIT1 interrupt at 500usec, which always needs to happen, it should never be missed,


After some analysis, I realized that I miss PIT1 interrupt, every 5 msec, which is the tick period.

I would assume that the scheduler runs every tick, and it will disable all interrupts to see if it has to scheudle or run a task.


Does anyone have any inputs on this issue?
