I am using LPC4330 Xplorer board and Invensense sensor.
The sensor requires back to back transactions (at least two) to complete register read/write operations.
First transaction is address with read/write indication and second transaction is data.
What I meant by back to back is CS should be de-asserted for 16 cycles.
When I fill SPI FIFO with two words (SPI is configured for word length as 8), I expected CS to be de-asserted for contentious 16 clocks but looks like its not.
When I set SPI word length as 16 and write one entry to SPI FIFO, I see transaction happening correctly to the sensor.
Please let me know how do I achieve burst transactions with SPI.
By the way, I am not using DMA mode.
