Multilayer interconnect matrix (BUSMATRIX)

Doc ID 022640 Rev 3

In the miscellaneous register bank, eight registers are allocated (ICM_x_ARB_CFG), one

for each ICM.

These registers have all the same layout:

●

The 31st bit is in charge of choosing the arbitration scheme: fixed priority or round robin

●

Bits [30:28] specify the priority starting level in case of round robin arbitration protocol

●

Then 3 bits are allocated to each layer to set the priority level in case of fixed priority

scheme: bits [2:0] for Layer0, [5:3] for Layer1 and so on.
