13.3.30 DCP Channel 3 Status Register (HW_DCP_CH3STAT)
The DCP Channel 3 Interrupt Status register contains the interrupt status bit and the tag of
the last completed operation from the command chain. If an error occurs during processing,
the ERROR bit is set and an interrupt is generated.
HW_DCP_CH3STAT: 0x1E0
HW_DCP_CH3STAT_SET: 0x1E4
HW_DCP_CH3STAT_CLR: 0x1E8
HW_DCP_CH3STAT_TOG: 0x1EC
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.
