psoc controller reset in sleepmode
I am using PSOC controller cy8c3244pvi-133
i am putting it in sleep mode and wakeup only when PICU interrupt occures.
when it wakes up i start 1msec timer interrupt and set one flag which I use for changing the state in while(1) loop.
my sleep current is 40usec. and active current is 20mA
I have noticed that when there is any transition of pins other than external interrupt pins PICU, controller wakes up and current is also increases.
for this I wrote a code such as if by accident controller wakes up then start 1msec timer interrupt and again go back to sleep but my interrupt is not working and even if I directly put to sleep mode, it is not going to sleep.
why this is happening?
