I've been trying to figure out this one for hours and I can't see what I'm missing. I currently am debugging my program on hardware and I have set a break-point inside of one of the functions called by SysTick_Handler(). Despite having the CPU halted, my LEDs, which are controlled by the CPU on the low side, are "blipping" about every second. I tried setting a break-point in the function that controls these and nothing happens which I would expect since my only core is halted.
Shouldn't my device be stable when halted since the gpio registers are not being modified by my code? Does the timer interrupt continue to fire even though I'm at a breakpoint or something?
