System Control module used for miscellaneous system configurations.
Module Operation
The SysCtl module is a conglomeration of miscellaneous system control modules that do not fit into any specific hardware peripheral.
Some of the functionalities of the SysCtl module include:
- Configure and enable/disable NMI sources
- Retrieve the SRAM/Flash size through software calls
- Disable/enable SRAM banks completely as well as disable retention during sleep
- Enable/disable GPIO glitch filters
- Change the type of reset that occurs on a WDT violation
Programming Example
The DriverLib package contains a variety of different code examples that demonstrate the usage of the SysCtl module. These code examples are accessible under the examples/ folder of the SDK release as well as through TI Resource Explorer if using Code Composer Studio. These code examples provide a comprehensive list of use cases as well as practical applications involving each module.
Below is a very brief code example showing how to retrieve the Flash and SRAM sizes using a software API. This is useful if the programmer is making a program that is meant to be run on multiple devices in the MSP432 family with different memory footprints.
