TM4C1237H6PM: GPIO 5V Tolerant

Part Number: TM4C1237H6PM

Hi E2E,

Good day!

A customer of mine tested their TM4C1237H6PM with 15k pull-up resistors. Pins PA6 and PA7 display different voltages, 4.85v and 3.6v respectively. However, on the datasheet, GPIOs are 5V tolerant. Is there any possible explanation for this?

Thank you for your support.

Best regards,

Franz
