My Controller is NXP MKE04Z128VLH4 with ARM Cortex M0+ where I have initialised two timer interrupt one is 625 us and the next is 1 ms.And when I'm observing the 625 us timer interrupt by toggling a GPIO Pin and using DSO, I'm observing flucatuation but at the same time if I'm disabling 1 ms timer interupt ,625us interupt is not showing any fluctatuation. I have tried assigning priority to both as 1 and 0 using NVICSetPriority but still issue not got solved.Is this an effect of Interrupt Latency and can it be solved by tail chaining. If yes how to implement Tail Chaining?
Hello Brince,
Can you try to assign same priority to the two timer interrupt? also 625 us timer interrupt has lower exception number than the 1 ms one.
