Example Summary

The following example configures TimerG in periodic mode and toggles the LED every 500ms. The device remains in SLEEP mode while waiting for an interrupt.

Pin	Peripheral	Function	LaunchPad Pin	LaunchPad Settings
PA0	GPIOA	PA0	J1_10	This pin is 5V tolerant open-drain and requires pull-up. J2 ON/OFF: Connect/Disconnect LED1 J10 1:2 5V Pull-up J10 2:3 3.3V Pull-up
PA20	DEBUGSS	SWCLK	J2_13	J101 15:16 ON: Connect to XDS-110 SWCLK (debug)

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.

Example Usage

Compile, load and run the example. LED1 will toggle every 500ms, and the device will remain in SLEEP while waiting for an interrupt.
