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 programmers view.

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.

Ensure that you access the GPV using non-cacheable transactions.

Note

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