When the output of an overlay is stored in memory through the write-back pipeline in capture mode, the bit field IDLENUMBER is ignored since a timing generator is used to time the transfer. The number of IDLE cycles is IDLENUMBER (from 0 to 15) if IDLESIZE = 0. The number of IDLE cycles is IDLENUMBERx8 (from 0 to 120) if IDLESIZE = 1 and BURSTSIZE = 2. The number of IDLE cycles is IDLENUMBERx4 (from 0 to 60) if IDLESIZE = 1 and BURSTSIZE = 1. The number of IDLE cycles is IDLENUMBERx2 (from 0 to 30) if IDLESIZE = 1 and BURSTSIZE = 0. | RW | 0x0 |

23 | ARBITRATION | Determines the priority of the write-back pipeline. The write-back pipeline is one of the high priority pipeline.

Shadow register, updated when DISPC_CONTROL2.GOWB is set to 1 by software and current WB frame is finished (no more data in the write-back pipeline), when the WB pipeline is directly connected to one of the pipelines (graphics or video), combined with the synchronization event of the channel overlay output selected as an input to the WB pipeline (that is, VFP start period of primary LCD, or VFP start period of secondary LCD, or VFP start period of the third LCD, or EVSYNC), for all registers associated with the selected channel out and further delayed by the DISPC_WB_ATTRIBUTES2.WBDELAYCOUNT bit-field, for all registers of the Write back and DMA. In WB capture mode, both DISPC_CONTROL2.GOWB and DISPC_CONTROL#.GOLCD/TV corresponding to the selected output channel shall be set.
