Global Variables
Although most of the variables and structure elements within the driver are supposed to be hidden
from the application code, there are several that provide information that might come in handy for
debugging. They are to be considered read-only by the application.

Structures Passed through RTOS Buffers
Interrupt Status Vector
This block captures the state of the device (during a POLL or during ISR processing) for use by
the Deferred-Processing Routine (DPR). It is the template for all device registers that are
involved in exception processing. It is the application’s responsibility to create a pool of ISV
buffers (using this template to determine the buffer’s size) when the driver calls the user-supplied
