3.2.1 Wait for Debug

Wait for debug is the most important configuration to implement when adding support for MSPM0 to any toolchain. Any reset performed upon the device post-configuration will still reset only the peripherals defined by the reset level, but it will remain in the reset-handler post reset. This is to ensure that the device does not go back into the application unless the user wishes to continue with application execution. This configuration is especially useful when flashing a device or debugging an application as it throws the device back into a known state and halts it.
