Pin	Peripheral	Function	LaunchPad Pin	LaunchPad Settings
PA14	GPIOA	PA14	N/A	PA14 is connected to S2 button to GND with no external pull resistor Press `S2` button to connect pin to GND Don’t use `S2` button if not needed by application
PA3	GPIOA	PA3	J2_19	N/A
PA7	GPIOA	PA7	J2_18	N/A
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
PA27	GPIOA	PA27	J4_37	PA27 can be connected to LED2 Blue `J13 ON` Connect to LED2 Blue `J13 OFF` Disconnect from LED2 Blue
PA9	UART0	RX	J1_3	PA9 can be used as UART RX connected to XDS-110 backchannel or to boosterpack connector: To use backchannel UART on J101: `J17 1:2`: Connects XDS-110 backchannel UART RX to `J101` `J101 7:8` Connects XDS-110 backchannel to UART RX To use UART on boosterpack connector: `J17 2:3`: Connects UART RX to `J1_3`
PA8	UART0	TX	J1_4	PA8 can be used as UART TX connected to XDS-110 backchannel or to boosterpack connector: To use backchannel UART on J101: `J16 1:2`: Connects XDS-110 backchannel UART TX to `J101` `J101 9:10` Connects XDS-110 backchannel to UART TX To use UART on boosterpack connector: `J16 2:3`: Connects UART TX to`J1_4`
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

Connect the hardware that descriped in the document. Compile, load and run the example. Push the S2 button to start program MSPM0L1306. Note: if use software trigger need the application code(include software invoke) exist on the chip.
