Pin Peripheral Function LaunchPad Pin LaunchPad Settings
PA0 GPIOA PA0 J1_10
  • PA0 is 5V tolerant open-drain so it requires pull-up
    • J10 2:3 Use 3.3V pull-up
    • J10 1:2 Use 5V pull-up

  • PA0 can be connected to LED1
    • J2 ON Connect to LED1
    • J2 OFF Disconnect from LED1
PA1 GPIOA PA1 J1_9
  • This pin can be used for testing purposes in boosterpack connector
    • Pin can be reconfigured for general purpose as necessary
  • PA1 is 5V tolerant open-drain so it requires pull-up
    • J19 2:3 Use 3.3V pull-up
    • J9 1:2 Use 5V pull-up
PA20 DEBUGSS SWCLK J2_13
  • PA20 is used by SWD during debugging
    • J101 15:16 ON Connect to XDS-110 SWCLK while debugging
    • J101 15:16 OFF Disconnect from XDS-110 SWCLK if using pin in application
PA19 DEBUGSS SWDIO J2_17
  • PA19 is used by SWD during debugging
    • J101 13:14 ON Connect to XDS-110 SWDIO while debugging
    • J101 13:14 OFF Disconnect from XDS-110 SWDIO if using pin in application

Device Migration Recommendations

This project was developed for a superset device included in the LP_MSPM0L1306 LaunchPad. Please visit the CCS User’s Guide for information about migrating to other MSPM0 devices.

Low-Power Recommendations

TI recommends to terminate unused pins by setting the corresponding functions to GPIO and configure the pins to output low or input with internal pullup/pulldown resistor.

SysConfig allows developers to easily configure unused pins by selecting Board→Configure Unused Pins.

For more information about jumper configuration to achieve low-power using the MSPM0 LaunchPad, please visit the LP-MSPM0L1306 User’s Guide.

Example Usage

Compile, load and run the example. The flash operations will start automatically when the example is run. If all flash operations complete, the LED will turn on. The application will stop at a breakpoint so the user can verify the values in memory match those expected in the comments.
