Chapter 5 - ADB Manager / ADB Manager Reference
ADB Manager Routines

Communicating Through the ADB

You can use the ADBOp function to communicate with devices on the ADB. In general, however, you shouldn't need to call ADBOp. 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 call ADBOp only occasionally for special purposes, such as setting device modes or obtaining device status.
