Hi experts,
My customer wants to know the difference between the internal resistance values of P1.0 and P1.3.
They measured the internal resistance values of P1.0 and P1.3 when the MSP430 was powered off.
As a result, P1.0 was 24kΩ and P1.3 was 2.4kΩ.
Can you explain the difference between the internal resistance values of P1.0 and P1.3?
If the information is not publicly available, I will tell the customer that it is not publicly available.
Best regards,
Sasaki
Hi Sasaki,
This value should about 35KR(Typical), and if there are some different, you can check if there are some other circuit in board.
Thanks!

Hi Sasaki-san,
The pull-up/down resistor is disable by default:
How to measure this value? Power off and using voltage meter(one probe is GND, one probe is P1.0/P1.3)?
This should be input impedance.
I don't have FR5733, but I have been measured in FR5739 Lanuchpad, the input impedance of P1.0 & P1.3 is all about 2.9MR.
Thanks!
Best Regards
Johnson
