Input Processing Pipe Link Connection x Control (IPPLC6CTL) – Offset 9b0
This register controls the operation on the link connection end of the processing pipe.
| Bit Range | Default | Access | Field Name and Description |
|---|---|---|---|
| 31:24 | 0h | RO | Reserved (Preserved) (RSVD31) SW must preserve the original value when writing. |
| 23:20 | 0h | RW | Stream Number (STRM) This value reflects the Tag associated with the data being transferred on the link. |
| 19:2 | 0h | RO | Reserved (Preserved) (RSVD19) SW must preserve the original value when writing. |
| 1 | 0h | RW/V | Stream Run (RUN) When set to 1 the DMA engine associated with this stream will be enabled to transfer data between FIFO and main memory. The SSYNC bit must also be cleared in order for the DMA engine to run. For output streams, the cadence generator is reset whenever the RUN bit is set. |
| 0 | 0h | RW/V | Stream Reset (SRST) Writing a 1 causes the corresponding stream to be reset. The Stream Descriptor registers (except the SRST bit itself) and FIFO's for the corresponding stream are reset. After the stream hardware has completed sequencing into the reset state, it will report a 1 in this bit. Software must read a 1 from this bit to verify that the stream is in reset. Writing a 0 causes the corresponding stream to exit reset. When the stream hardware is ready to begin operation, it will report a 0 in this bit. Software must read a 0 from this bit before accessing any of the stream registers. The RUN bit must be cleared before SRST is asserted. |
