4.3 Device Management
The device management is a set of API functions that are used by the application to control the
device. These functions take care of initializing a device in a specific configuration, enabling the
device general activity as well as enabling interrupt processing for that device. They are also used
to change the software state for that device. For more information on the device states see the
state diagram on page 19. For a typical device management flow diagram see page 22.
Adding a Device: suni4x622Add
This function verifies the presence of a new device in the hardware then returns a handle back to
the user. The device handle is passed as a parameter of most of the device API Functions. It’s
used by the driver to identify the device on which the operation is to be performed.
