I want to use REG0 to supply 1.8v to external 4.7k pull-ups including when the system is off. Looking at the product specification REG0 can supply 1mA while in system off. If one pulled-up line goes low the resistor would consume 0.38mA. I will have six lines and all will be capable of waking up the system.
My concern is that if 3 or more lines are pulled low before the system wakes up then the resistors will consume too much current. I'd hate to implement a regulator just to power some pull-ups. Do you think the system can wake fast enough to handle the current if 3 or more lines are activated simultaneously or should I implement an external power solution?
