Gents, the 150uA additional current and the fact that only a power cylce removes it sounds like the JTAG LDO is somehow turned on. This can happen on applicaiton level if a pulse between 1 ns and ~50us...

Reducing the differential external reference voltage will make the voltage for each ADC step smaller, i.e., increase the precision, but I'd guess that due to noise, the results will not be more...

The FR2533 has 19 GPIOs, but how many buttons are supported depends on how they are connected, and how many pins you can actually use for them.

I do not know why you think the CapTIvate pin was 19 pin. I know that the FR2533 has 16 GPIOs. How do you think? I would like to know the performance of CapTIvate IP. Can MSP430FR2533 detect the 16...

Then you'd have to use a different TASSEL value.
