	Field Name	Field Type	Field Description

Device Initialization Vector: DIV

Passed via the suni4x622Init call, this structure contains all the information needed by the driver to initialize a S/UNI-4x622 device. This structure is also passed via the suni4x622SetInitProfile call when used as an initialization profile.

•valid indicates that this initialization profile has been properly initialized and may be used by the USER. This field should be ignored when the DIV is passed directly.

•pollISR is a flag that indicates the type of interrupt servicing the driver is to use. The choices are ‘polling’ (SUNI4x622_POLL_MODE), and ‘interrupt driven’ (SUNI4x622_ISR_MODE). When configured in polling the interrupt capability of the device is NOT used, and the USER is responsible for calling suni4x622Poll periodically. The actual processing of the event information is the same for both modes.

•cbackSOH, cbackLOH, cbackRPOH, cbackPYLD, cbackFIFO, cbackIntfSys, cbackIntfLine and cbackAPS are used to pass the address of application functions that will be used by the DPR to inform the application code of pending events. If these fields are set as NULL, then any events that might cause the DPR to ‘call back’ the application will be processed during ISR processing but ignored by the DPR.
