MAX32630FTHR - GAINING ACCESS TO DIGITAL I/O PINS
I am having difficulty writing to pins P5_3 to P5_6. I should be able to set them up as Digital Outputs, right? I tried setting them as outputs, set HIGH, and after reset they go LOW. Even with a pull-up resistor. Something else, internal to the MCU or on the Eval board owns these pins. Has anyone seen this issue before?
Thank you.

Hello Bill,
P5.0 to P5.5 are tied to P4.2 to P4.7. Try setting P4.2 to P4.7 to Hi-Z by declaring them as DigitalIn with PullNone.
Thanks, Justin
