This will keep open/close state of MOSFET. Click to expand... You don't need a DFF. The MCU will keep it's I/O as you program it ... even in sleep mode. Klaus

Yeah, I just looked to the datasheet and it does say "State Held" even when MCU is when "Only RTC Counter" is on. In which case the power consumption is just 0.66uA!

I'm not sure I can handle it Same with MSP430FR2000IRLL... I think I'll need to order it more, just to train to solder it...
