Fork of MAX32620FTHR by Jesse Marroquin

The MAX32620FTHR platform library provides board level functions for the MAX32620FTHR platform. The MAX32620 ARM Cortex-M4F microcontroller provides two I/O supply rails, VDDIO and VDDIOH. The MAX32620FTHR platform supplies VDDIO at 1.8V and VDDIOH at 3.3V. After reset all GPIO pins will use VDDIO.
