PIT Timers reliability : How can PIT timers shift over time?

I am using a MPC5604P and have implemented some real time sequencer managing 2 tasks using Periodic Interrupt Timer (PIT) interrupts.


How could each PIT timer deviate over time?


I am initializing PIT0 interrupt as a 200ms task and PIT1 as 1sec task without further reconfiguration once tasks are scheduled.

I'm checking against each task interrupt re-entrance.


I see the initial start delay between PIT interrupts as minor but wonder how this delay can vary over time.


Thank you.
