A.6 Configuration input signals

The following table shows the configuration input signals. All these signals must be stable at least ten cycles before deassertion of reset and must remain stable throughout the operation of the CCN-502, until a following reset assertion or powerdown, if any.

Table A-18 Configuration input signals

Signal Type Description Connection information
General configuration input signals  
PERIPHBASE[43:24] Input Base address of the CCN-502 configuration register space. Tie as required for system memory map.
SBSX_128_n256 Input Controls the data width of RDATA_M and WDATA_M for the SBSX AXI4 interfaces:
0256-bit effective data width.
1128-bit effective data width. Uses the least-significant 128 bits. The upper 128 bits are undriven and unsampled.

Note:

The physical bus width is always 256 bits.
Tie as required for system MC data width.
