• CDC_PND: Pending Codec Request (this bit is a status bit)
0: Indicates that no Codec request is pending.
1: Indicates that the request has been taken into account but cannot be serviced within the current frame. The operation is post-
poned to the next frame.
• VSYNC: Vertical Synchronization
1: Indicates that a Vertical synchronization has been detected since the last read of the status register.
• PXFR_DONE: Preview DMA Transfer has Terminated.
When set to one, this bit indicates that the DATA transfer on the preview channel has completed. This flag is reset after a read 
operation.
• CXFR_DONE: Codec DMA Transfer has Terminated.
When set to one, this bit indicates that the DATA transfer on the codec channel has completed. This flag is reset after a read 
operation.
• SIP: Synchronization in Progress (this is a status bit)
When the status of the preview or codec DMA channel is modified, a minimum amount of time is required to perform the clock 
domain synchronization. This bit is set when this operation occurs. No modification of the channel status is allowed when this bit 
is set, to guarantee data integrity.
