Split/Retry: Do all masters have to support SPLIT and RETRY?

Applies to: AHB

Answer

Yes. All masters must support SPLIT and RETRY responses to ensure they are compatible with any bus slave. A master will handle both SPLIT and RETRY responses in an identical manner.

Note that if the system is based on AHB-Lite, SPLIT and RETRY responses are not supported. AHB-lite is a single master solution, so SPLIT and RETRY responses would have no meaning.
