Why am I not able to see Pre-emption settings in BSP Drivers when using IIC? - Why am I not able to see Pre-emption settings in BSP Drivers when using IIC? Description Auto Pre-emption does not support Internal Interrupt Controller of NIOS II ® processor. There was a problem with the documentation. Resolution To be able to use Pre-emption feature, Vectored Interrupt Controller would be the only solution to do so, since IIC does not support pre-emption features. The documents will be updated to clarify the IIC support issue of pre-emption.
