Part Number: MSP430FR5994
1) MSP430FR5994 datasheet defines max digital I/O leakage of +/- 20 nA, tryinf to verify this using MSP-EX430FR5994 eval kit but getting 90 nA instead. Is this because I am using multi-function pins that have analog components (even though pin configured as digital I/O)? I would like to know this before building a board. I need to be able to verify/quantify max leakage across this multipurpose pins and confirm that the leakage would go down to +/- 20 nA if I only use digital I/O pins on my design.
2) while experimenting, we measured ADC_12 pins and noticed that there was a DC offset coming from the MSP430 if we didn’t use a strong enough resistor to connect the voltage appropriately. We are using the internal VREF of 2.5V and tried to measure a voltage of 0.72V via a 100K resistor. The resistor side closest to the MSP430 was reading 0.8V. Is this DC offset normal (sounds a bit high)? Can we use the ADC offset information on the device descriptor to account for this in our software if needed?
Thank you in advance
