Does Nios II 1.1 support Interprocessor Mailbox?

Hello all,

I am wondering if the Nios II 1.1 processor supports interprocessor mailbox functions.

We could find a section named "Interprocessor Mailbox" in the content menu of the Nios II hardware handbook.

However, I was not able to find any related descriptions in the handbook, or any files in the "components" folder.

I would appreciate any information.

Reference: Nios II Processor Reference Handbook (NII5V1-1.2, December 2004)
