In the Miscellaneous register bank are allocated eight register (ICM_x_ARB_CFG) one for
each ICM.
These registers have all the same layout:
●
The 31th bit is in charge of choosing the arbitration scheme: fixed priority or round robin
●
Bit [30:28] specifies the priority starting level in case of round robin arbitration protocol
●
Then 3 bit are allocated to each layer to set the priority level in case of fixed priority
scheme: bit [2:0] for Layer0, [5:3] for Layer1 and so on. Refer to table 4 for layer list.
