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.
