//
// Step 1. Initialize System Control:
// PLL, WatchDog, enable Peripheral Clocks
// This example function is found in the F2837xD_SysCtrl.c file.
//
   InitSysCtrl();

#ifdef _STANDALONE
#ifdef _FLASH
//
// Send boot command to allow the CPU2 application to begin execution
//

//
// Send boot command to allow the CPU2 application to begin execution
//
IPCBootCPU2(C1C2_BROM_BOOTMODE_BOOT_FROM_RAM);
#endif
#endif

//
// Call Flash Initialization to setup flash waitstates
// This function must reside in RAM
//
#ifdef _FLASH
   InitFlash();
#endif

//
// Step 2. Initialize GPIO:
// This example function is found in the F2837xD_Gpio.c file and
// illustrates how to set the GPIO to it's default state.
//
    InitGpio(); // Skipped for this example

    GPIO_SetupPinOptions(34, GPIO_OUTPUT, GPIO_PUSHPULL);

//
// TODO Add code to allow configuration of GPADIR from CPU02 using IPC
//
    EDIS;
    GpioDataRegs.GPADAT.bit.GPIO31 = 1;// turn off LED

//
// Step 3. Clear all interrupts and initialize PIE vector table:
// Disable CPU interrupts
//
    DINT;

//
// Initialize the PIE control registers to their default state.
// The default state is all PIE interrupts disabled and flags
// are cleared.
// This function is found in the F2837xD_PieCtrl.c file.
//
    InitPieCtrl();

//
// Disable CPU interrupts and clear all CPU interrupt flags:
//
    IER = 0x0000;
    IFR = 0x0000;

//
// Initialize the PIE vector table with pointers to the shell Interrupt
// Service Routines (ISR).
// This will populate the entire table, even if the interrupt
// is not used in this example.  This is useful for debug purposes.
// The shell ISR routines are found in F2837xD_DefaultIsr.c.
// This function is found in F2837xD_PieVect.c.
//
    InitPieVectTable();

//
// Enable global Interrupts and higher priority real-time debug events:
//
    EINT;  // Enable Global interrupt INTM
    ERTM;  // Enable Global realtime interrupt DBGM

//
// Step 6. IDLE loop. Just sit and loop forever (optional):
//
    for(;;)
    {
        //
        // Turn on LED
        //

        //
        // Delay for a bit.
        //
        DELAY_US(1000 * 500);

        //
        // Turn off LED
