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 Fixed Clock Generation (FXU) is one of its subunits and it provides five predefined non-configurable clocks for GTM modules, including the TOM. 2019-10-17 Copyright © Infineon Technologies AG 2019.

- Page 6 › The function IfxGtm_Tom_Timer_init() initializes and activates the TOM with the given configuration. All the functions used for the configuration of the TOM are provided by the iLLD header IfxGtm_Tom_Timer.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_Tom_Timer_acknowledgeTimerIrq() (iLLD header IfxGtm_Tom_Timer.h). › Change the LED state by calling the function IfxPort_togglePin() (iLLD header IfxPort.h). 2019-10-17 Copyright © Infineon Technologies AG 2019.
