DCP channel 3 status register
| HASH_MISMATCH | This bit indicates that a hashing check operation is mismatched for the control packets that enable the HASH_CHECK bit |
| ERROR_SETUP | This bit indicates that the hardware detected an invalid programming configuration (such as a buffer length that is not a multiple of the natural data size for the operation) |
| ERROR_PACKET | This bit indicates that a bus error occurred when reading the packet or payload or when writing the status back to the packet paylaod |
| ERROR_SRC | This bit indicates that a bus error occurred when reading from the source buffer |
| ERROR_DST | This bit indicates that a bus error occurred when storing to the destination buffer |
| ERROR_PAGEFAULT | This bit indicates that a page fault occurred while converting a virtual address to a physical address |
| ERROR_CODE | Indicates additional error codes for some of the error conditions. 1 (NEXT_CHAIN_IS_0): Error is signalled because the next pointer is 0x00000000. 2 (NO_CHAIN): Error is signalled because the semaphore is of a non-zero value and neither of the chain bits is set. 3 (CONTEXT_ERROR): Error is signalled because an error was reported while reading/writing the context buffer. 4 (PAYLOAD_ERROR): Error is signalled because an error was reported while reading/writing the payload. 5 (INVALID_MODE): Error is signalled because the control packet specifies an invalid mode select (for example, blit + hash). |
| TAG | Indicates the tag from the last completed packet in the command structure. |
