Need some clarification regarding Interrupt Controller - eMios

[kyf]

Hello NXP team!

Regarding the screenshot bellow:

1. Is EMIOS0_0_IRQn refered to eMios 0 channel 0 ?? or this is an other interrupt ?

2. Is there any document where I can find descriptions regarding the eMios interrupts except reference manual ?

3. Is interrupt priority set only withing the "peripheral tool" ?

4. Is there any handler for handling the priorities of the interrupts and their priorities ? OR this is done by hardware ?

Kind regards,

kyf

Hi, PetrS,

We are getting an error - "Undefined reference to emios0_3_irq" while generating code in MBDT with S32DS for generating variable frequency and variable duty cycle PWM pulse.

Kindly help me for resolving this error.

Thanks & Regards,

Hi,

1) four channle's interrupt requests are ored into single vector in eMIOS and EMIOS0_0_IRQn belongs to channels 23,22,21,20
2) it is in S32K3xx_interrupt_map.xlsx attached to the RM, also visible in project 

3-4) priority is set either in the component you shown or a IntCtrl_Ip_SetPriority function can be used, i think.
