5.1.1. HDRX signals

Table 5.2 lists the signals on the HDRX pins for the CT-R4F and EB baseboard. The CT-R4F AXI master port signals are multiplexed onto the pins on this header.

For a description of the AXI bus signals see AMBA 3 AXI Protocol Specification (ARM IHI 0022).

Note

The signal on the lower header of a Core Tile is named XLn. For example, the pin 1 signal for the lower header is XL90 and the corresponding CT-R4F signal is ARADDR13 / ARADDR29. This example also illustrates the designation used for a multiplexed signal, X / Y where signal X is present when CLK_OUT_MINUS1 is HIGH and signal Y is present when CLK_OUT_MINUS1 is LOW. See AXI bus multiplexing for further details of the AXI signal multiplexing.

For the EB there are two HDRX headers (tile site 1 and tile site 2). For tile site1 the HDRX pin number prefix is T1X.
