Note

In Figure 3:

  • The read channel, write channel, and low-power interface signals are standard AMBA AXI signals that the AMBA AXI Protocol Specification describes. The signal names are appended with:

    • the letter M for signals that connect to the component master interface

    • the letter S for signals that connect to the component slave interface.

  • The scan signals are not shown.

Table 4 lists the non-standard AXI and scan signals.
