How to reduce Interrupt-Jitter

Hello to everyone. This is my Code: void FIQ_Handler(void) __irq { T1CLRI = 0x55; // T1CLRI is an 8-bit register. // Writing any value to this register clears the Timer1 interrupt. GP4SET = 0x00040000;...

Interrupt latency while STR/LDR in cortex-M3

Hi, What is the expected behaviour on M3 when issuing STR/LDR to some remote memory (AHB) and interrupt arrive? is the interrupt being delayed although this is normal memory and this command can re...
