Detailed Description

6.8.1.3

Hard Reset

The hard reset resets all modules that are set up or modified by the application. This includes all

peripherals and the nondebug logic of the Cortex-M4. MSP432P4x1x devices support up to 16 sources of

hard reset. Table 6-41 lists the reset source allocation. The Reset Controller registers can be used to

identify the source of reset in the device. For further details, see the Reset Controller chapter in the

MSP432P4xx SimpleLink™ Microcontrollers Technical Reference Manual.

(1)

The WDT_A generated resets can be mapped either as a hard reset or a soft reset.

(2)

The flash controller can generate a reset if a voltage anomaly is detected that can corrupt only flash

reads and not the rest of the system.

(3)

Reserved indicates that this source of hard reset is currently unused and left for future expansion.

(4)

The CS cannot initiate a hard reset, but if a hard reset occurs during clock source or frequency

changes, the CS can extend the reset to allow the clocks to settle before releasing the system. This

reduces the chance of nondeterministic behavior.

(5)

The PCM cannot initiate a hard reset, but if a hard reset causes power mode changes, the PCM can

extend the reset to allow the system to settle before releasing the Reset. This reduces the chance of

nondeterministic behavior.
