Sleep Modes(sleep_modes) This example demonstrates the different power modes available on the Tiva C Series devices. The user button (USR-SW1) is used to cycle through the different power modes. The SRAM, Flash, and LDO are all configured to a lower power setting for the different modes. A timer is configured to toggle an LED in an ISR in both Run and Sleep mode. In Deep-Sleep the PWM is used to toggle the same LED in hardware. The three remaining LEDs are used to indicate the current power mode. LED key in addition to the toggling LED: 3 LEDs on - Run Mode 2 LEDs on - Sleep Mode 1 LED on - Deep-Sleep Mode UART0, connected to the Virtual Serial Port and running at 115,200, 8-N-1, is used to display messages from this application. ------------------------------------------------------------------------------- Copyright (c) 2014 Texas Instruments Incorporated.
