Ultra Low Power

Hi guys,

on of the reasons for using the MSP430 is its ultra low power consumption but it is hard to find a short overview how to  handle the IOs. My question is: If I go to LPM4 and only wake up through reset, how should I handle the IO Pins? Disconnect all pull ups/down? Make them input or output? My idea is, make them all outputs and write P1OUT and P2OUT to zero? Anything else important? I want to use a CR2032 and I think I do not need a power switch.

Greetings Sven
