3.6.5 DMA OPERATION
Set DMA control registers to configure the DMA operation. The DMA engine begins to transfer data after setting
the Transfer Run (TR) bit of the DMA Transfer Command (DMA_TRANS_CMD) register to 1. The Transfer Busy
(TB) bit of the DMA Transfer Status (DMA_TRANS_STATUS) register is maintained as 1 during the data transfer
to indicate that the DMA engine is busy. After the DMA operation has been finished successfully, the Transfer
Done (TD) bit of the DMA Transfer Status (DMA_TRANS_STATUS) register is set to 1 to notify the system
software that the DMA operation is completed. There are two methods, with which the system software waits for
the completion of the DMA operation and determines the DMA engine’s completion status.
•
DMA operation with a polling method
•
DMA operation with an interrupt-driven method
3.6.5.1 DMA Operation With a Polling Method
The system software polls DMA_TRANS_STATUS register to check the status of the DMA engine.
The DMA engine sets the TD bit of the DMA Transfer Status (DMA_TRANS_STATUS) register to 1 when the data
transfer is completed. It sets the Transfer Error (TE) bit of the DMA Transfer Status (DMA_TRANS_STATUS)
register to 1 when an error occurs during the transfer.
