Hi,

I enter sleep mode when my program has nothing to do.

Before I enter SLEEP MODE i change the clk to the RTC and when I exit

I switch back to OSC CLK.

problem:

the time it takes from exiting sleep to changing the back to OSC clk is very long aroung 10ms even if I use FIQ.

I change the CLK in the WIU interrupt because thids intterupt ocures emidiatly after exiting sleep mode.

how can i reduced the WIU interrupt latancy to minimum?

is it posible to enable WIU to exit from SLEEP but not to jump to the

interrupt.
