ABSTRACT:
When a master device resets, flush commands are issued to a flush master register in the slave devices. A comparator compares the identification of the master device associated with the flush command to an identification of the master device associated with data for return by the slave device. A gate is responsive to the comparator to flush data from the data register that are pending for return.
