Page 2: Scope Of Work
LED. The Generic Timer Module triggers an interrupt every 500 ms. The state of the port pin, where the LED is connected, is toggled inside the Interrupt Service Routine (ISR). 2019-10-17 Copyright © Infineon Technologies AG 2019. All rights reserved. - Page 3 The Clock Management Unit (CMU) is responsible for clock generation of the GTM. The Configurable Clock Generation Subunit (CFGU) provides eight clock sources for the GTM submodules TIM, TBU, MON and ATOM. 2019-10-17 Copyright © Infineon Technologies AG 2019. All rights reserved.

- Page 6 The LED configuration is also done in the function initGtmAtom(): › Set the port pin mode to output and push-pull by calling the function IfxPort_setPinModeOutput(), provided by iLLD header IfxPort.h. 2019-10-17 Copyright © Infineon Technologies AG 2019. All rights reserved.
- Page 7 The ISR implemented in this example contains the following steps: › Clear the timer event with the function IfxGtm_Atom_Timer_acknowledgeTimerIrq() in the iLLD header IfxGtm_Atom_Timer.h › Change the LED state by calling the function IfxPort_togglePin() in the iLLD header IfxPort.h 2019-10-17 Copyright © Infineon Technologies AG 2019.
