Abstract: A method of improving synchronization over a secure digital (SD) bus between an SD host and an SD client device is described. The method includes writing to a client event register to interrupt the SD host for an SD extended command. The method also includes triggering the SD host to issue the SD extended command to the SD client device over the SD bus in response to the SD client device writing to the client event register.
