The PDMA will accept data across the Tx PSI-L Interface in accordance with the physical handshaking protocol as defined in the PSI-L Interface specification. The value sources for the output pins on the PSI-L interface are described in the following table.
Pin | Output Value / Source From PDMA |
---|---|
strm_i_link | This signal is asserted high to indicate the PSI-L link is valid. |
strm_i_ready | This signal is asserted high anytime there is space in the PSI-L ingress fifo. |
strm_i_sreq | This signal is asserted high anytime there is credit return data waiting in the PSI-L status fifo. |
strm_i_sthreadid | This is set to the local destination thread that is returning credit. |
strm_i_sccnt | This is set to the number of credits being returned, or 0 on a TX teardown acknowledgement. |
