    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.
