5.8.6.5.7.2. Transfer Argument Data Structure
Transfer argument data structure is used to provide payload-related information. This data structure must be used when the external DMA is used to get the payload bytes.
BIT-FIELD | FIELD NAME | WIDTH | DESCRIPTION |
---|---|---|---|
31:16 | DL | 16 | Data Length This field is used to indicate the data length of the transfer. For CCC transfers, it is expected that the correct length be programmed. The master controller deals with all CCCs transparently. |
15:8 | DB | 8 | Defining Byte Value DB indicates the 8-bit defining byte to be transferred in the CCC transfer. This byte is valid only when both CP and DBP bits are enabled, otherwise the controller ignores this byte. |
7:3 | RESV | 5 | Reserved |
2:0 | CMD_ATTR | 3 | Command Attribute Defines the command Ty0: transfer command
