PWM ISR is not handle by the controller

[Basavanagouda1]

Hi All,

We are using SPC560pxx series development board and it is configured with SPI,CAN,UART,ADC,DMA,PWM,ICU and other modules.

We initialized the PWM, it's running proper for few seconds. But after some time, PWM stops generating interrupts. We checked it by toggling GPIO in the ISR.

We have some confusions to understand it.  

1. How the controller is ignoring PWM interrupt?

2. How we can make user controller should handle all the interrupts. 

3. How we can sequence the ISR handling?

Please help me to solve this problem.

Thanks,

Basava.

Hello ,

in the SPC5Studio tools suite ,

there are PWM examples

Check your pinmap and PCTL
