Race condition in mailbox registers resulting in events miss

Details:

Potential race condition in capture registers resulting in events getting lost while other events in the same register are being cleared by writing to the register. Following registers are impacted by this issue:

MSS_CTRL: *_MBOX_READ_REQ

MSS_CTRL: *_MBOX_READ_DONE

Workaround(s):

Read the status(READ DONE / READ_DONE_REQ) of the other processor to check any interrupt is in flight before setting up the trigger (WRITE DONE /READ ACK) event (OR)

Re-trigger the (WRITE DONE /READ ACK) event if the status (READ DONE / READ_DONE_REQ) is not received within the given time
