HW_DCP_CH0STAT_TOG: 0x12C
The interrupt status register is updated at the end of each work packet. If the interrupt bit
is set in the command packet's command field, an interrupt will be generated once the packet
has completed. In addition, the tag value from the command is stored in the TAG field so
that software can identify which command structure was the last to complete. If an error
occurs, the ERROR bit is set and processing of the command chain is halted.

NEXT_CHAIN_IS_0 — Error signalled because the next pointer is 0x00000000
NO_CHAIN — Error signalled because the semaphore is nonzero and neither chain bit is set
CONTEXT_ERROR — Error signalled because an error was reported reading/writing the context
buffer
PAYLOAD_ERROR — Error signalled because an error was reported reading/writing the payload
INVALID_MODE — Error signalled because the control packet specifies an invalid mode select (for
instance, blit + hash)
