DCP channel 0 status register
| HASH_MISMATCH | This bit indicates that a hashing check operation 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 payload |
| 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 the additional error codes for some of the error conditions 1 (NEXT_CHAIN_IS_0): Error signalled because the next pointer is 0x00000000 2 (NO_CHAIN): Error signalled because the semaphore is non-zero and neither chain bit is set 3 (CONTEXT_ERROR): Error signalled because an error is reported reading/writing the context buffer 4 (PAYLOAD_ERROR): Error signalled because an error is reported reading/writing the payload 5 (INVALID_MODE): Error signalled because the control packet specifies an invalid mode select (for instance, blit + hash) |
| TAG | Indicates the tag from the last completed packet in the command structure |
