S32K3 - ICU EXT ISR WIFER Digital Filter Option

[ssean]

Hello.

I am currently reviewing the WKPU (Wakeup Unit) functionality triggered by external interrupts.

Will setting the ICU_EXT_ISR_WIFERDigital_Filter option to true provide any significant benefits in terms of noise immunity/robustness?

Additionally, I would like to inquire whether it is mandatory to set 'Standby Enable' to true in the SIRC configuration when this digital filter option is enabled.

Are there any additional settings that need to be configured?

BRs,

Sean Sung
