3.2. Configuration programmers model

The CoreLink NIC-400 Network Interconnect contains configuration registers, partitioned into a number of individual 4KB blocks that you can program using the Global Programmers View (GPV). The base address of each GPV region is set at configuration time in CoreLink ADR-400 AMBA Designer.

You can configure any slave interface to have access to all of the registers in the GPV.

The following restrictions apply to accessing the GPV. The GPV:

Note

  • Any registers that a switch requires are implemented within the register block of the associated Interface Block (IB). If no IB is attached, then you can configure an IB to specifically provide programmable registers.

  • Before you access the GPV, you must ensure that all clocks are running.
