      SPI example is a demo example and do not handle all possible conditions. The intention of this demo code is to demonstrate possible use of the driver

      When operating in interrupt mode with FIFO enabled and operating as master. When the transfer length is not multiple of the configured FIFO depth, some of last words are not transmitted.

      Some debug point to note - the ISR takes a snap shot of the pending ints and clear them without checking if these ints have been re-triggered.
