Multimedia bridge, high performance
Scaler and PCI circuit (SPCI)
SAA7146A
Each interface, A1 and A2, uses its own Time Slot List (TSL) when working independently of each other. The shaded
areas are valid for combined processing of TSL1 and TSL2 only. In these modes, TSL1 or TSL2 are used interleaved or
concatenated, to achieve one single TSL with up to 32 records. Both parts of the list control both interface circuits in
parallel. All four DMA channels are available. The TSLs are write only.
