ADUC703x - WU pin as GPIO

Hi,

 

As it always happens, I need one more GPIO.

I've looked at the WU pin.

 

There is a line "If the wake-up monoflop is disabled, the wake-up driver should be disabled after 1.3 sec" in the datasheet.

Can I omit this recommendation and switch the pin high as long as I need,

if the pin's load is very light (i.e., MOSFET gate)?

 

Another case - load is 12 mA (VDD = 12V).

How can I decide - this load is too high or not?

 

Best regards,

Alex
