Implementation

Configuring timers T2 and T4 to enable the reload of timer T3

Configurations of timers T2 and T4 are done once in the function initGpt12Timer() by the

following steps:

›

Configure timers T2 and T4 in reload mode by using the iLLD function

IfxGpt12_T2_setMode() and IfxGpt12_T4_setMode()

›

Set the trigger event for reload of timer T3 by using the iLLD functions

IfxGpt12_T2_setReloadInputMode() and IfxGpt12_T4_setReloadInputMode()

›

Set timer T2 value with the iLLD function IfxGpt12_T2_setTimerValue() and

dutyDownTime as parameter

›

Set timer T4 value with the iLLD function IfxGpt12_T4_setTimerValue() and

dutyUpTime as parameter

Starting timer T3

Finally, starting the timer T3 is done in the function runGpt12PWM() by calling the iLLD

function IfxGpt12_T3_run().

The above functions are provided by the iLLD header IfxGpt12.h.
