A DMA read/write operation requires bits TSEC_DMA_CMD_INIT and TSEC_DMA_CMD_READ/TSEC_DMA_CMD_WRITE to be set in TSEC_DMA_CMD.
A DMA read/write operation requires bits TSEC_DMA_CMD_INIT and TSEC_DMA_CMD_READ/TSEC_DMA_CMD_WRITE to be set in TSEC_DMA_CMD.
During the transfer, the TSEC_DMA_CMD_BUSY bit is set.
During the transfer, TSEC_DMA_CMD_STATUS is set to "Busy".
Accessing an invalid address causes bit TSEC_DMA_CMD_ERROR to be set.
Accessing an invalid address sets TSEC_DMA_CMD_STATUS to "Error".
