uint32_t	extraBytesTCR
	Used to write SPI TCR via DMA for extra 1 or 2 data byte transfer. Used to de-assert CS if DEASSERT_AFTER_LAST.
uint32_t	extraThirdByteTCR
	Used to write SPI TCR via DMA for extra 3rd data byte transfer. Used to de-assert CS if DEASSERT_AFTER_LAST.
uint32_t	pcsTCR
	Used to write SPI TCR via DMA to to de-assert CS if DEASSERT_AFTER_LAST at the end of the transfer.
DmaTcd	softwareTCD [6]
	SoftwareTCD, used for scatter/gather to de-assert CS, internally used.
