Communicating Through the ADB
You can use theADBOpfunction to communicate with devices on the ADB. In general, however, you shouldn't need to callADBOp. Applications should get information about the user's input on ADB devices by calling the appropriate Event Manager routines. In addition, the ADB Manager automatically polls device register 0 (the register that contains the data to be transmitted from the device to the ADB device handler) as part of its normal bus polling and service request handling. As a result, device handlers should need to callADBOponly occasionally for special purposes, such as setting device modes or obtaining device status.
