STM: Simple timeout wait with 64 bits

The example is quite similar to the previous one, but in this case, we utilize the 64-bit capability of the STM timer. The iLLD library provides a function to calculate the number of counts equivalent to milliseconds, thus avoiding the complexity of manual calculation.

#include "Ifx_Types.h"
#include "IfxCpu.h"
#include "IfxScuWdt.h"
#include "IfxPort_Io.h"
#include "IfxStm.h"

IFX_ALIGN(4) IfxCpu_syncEvent g_cpuSyncEvent = 0;

void core0_main(void)
{
    sint32 Ticks;

    IfxCpu_enableInterrupts();
    
    /* !!WATCHDOG0 AND SAFETY WATCHDOG ARE DISABLED HERE!!
     * Enable the watchdogs and service them periodically if it is required */
    IfxScuWdt_disableCpuWatchdog( IfxScuWdt_getCpuWatchdogPassword() );
    IfxScuWdt_disableSafetyWatchdog( IfxScuWdt_getSafetyWatchdogPassword() );
    
    /* Wait for CPU sync event */
    IfxCpu_emitEvent( &g_cpuSyncEvent );
    IfxCpu_waitEvent( &g_cpuSyncEvent, 1 );

    /*configure the pin */
    IfxPort_setPinMode( &MODULE_P00, 5, IfxPort_Mode_outputPushPullGeneral );
    IfxPort_setPinPadDriver( &MODULE_P00, 5, IfxPort_PadDriver_cmosAutomotiveSpeed1 );

    /*get the number of ticks need it to count up to 500 milliseconds
     * by default CPU0 frequency is set to 100MHz and the same frequency feeds the STM timer
     * this fucntions use these values to calculate how many ticks are required to count up to 
     * 500ms
     * Ticks = (100000 / 1000) * miliseconds = 50000     */
    Ticks = IfxStm_getTicksFromMilliseconds( &MODULE_STM0, 500u );

    while(1)
    {

        /*Flip the led on port 00 pin 5*/
        IfxPort_togglePin( &MODULE_P00, 5 );
        /*function internally will wait here reading the STM0 (for the CPU0), while
         * the number of ticks reach its count, which in turns has to be for a period
         * of time up to 500ms*/
        IfxStm_waitTicks( &MODULE_STM0, Ticks );
    }
}
