8.1.1.1 Hardware Circuit Design

Verify that the MSPM0 has the appropriate external capacitor in few power pins to run in a stable manner. Check the circuit connected to the VDD, Vcore (if supported), and NRST pin and the pin voltage.

Find reference circuits in the Basic Application Schematic section of device-specific data sheet. Expect that the Vcore voltage (if supported) is 1.35V (typical), representing that the internal PMU circuit for the digital core functions normally.
