Regarding IEBus, if a slave reception request (SLVRQ) is received during a master transmission request (such as DR setting, MSTRQ setting), can I first finish the slave reception start processing then resume the master transmission request?
Yes, you can.
Issue a master transmission request after performing the slave reception processing.
Note that the MSTRQ setting cannot be performed during a period of 61.7μs (forcible reset period) after defeat in a bus conflict.
(Refer to Caution 1 (p.562) in the manual (6th Edition).)
