SADDR : ECC DMA Source Address
The ECC accelerator supports DMA function to transfer the DATA and PARAMETER between SRAM memory space and ECC accelerator. The SADDR keeps the source address of the data buffer where the source text is stored. Based on the source address, the ECC accelerator can read the DATA and PARAMETER from SRAM memory space and do ECC operation. The start of source address should be located at word boundary. That is, bit 1 and 0 of SADDR are ignored. SADDR can be read and written. In DMA mode, software must update the CRYPTO_ECC_SADDR before triggering START.

DADDR : ECC DMA Destination Address
The ECC accelerator supports DMA function to transfer the DATA and PARAMETER between SRAM memory and ECC accelerator. The DADDR keeps the destination address of the data buffer where output data of ECC engine will be stored. Based on the destination address, the ECC accelerator can write the result data back to SRAM memory space after the ECC operation is finished. The start of destination address should be located at word boundary. That is, bit 1 and 0 of DADDR are ignored. DADDR can be read and written. In DMA mode, software must update the CRYPTO_ECC_DADDR before triggering START.

The address of the updated registers that DMA feeds the first data or parameter to ECC engine. When ECC engine is active, ECC accelerator does not allow users to modify STARTRE.G. for example, to update input data from register CRYPTO_ECC POINTX1. Thus, the value of STARTREG is 0x808.
