Table 32.  PMON_UIDT_L: Offset: (Block Stride * 8h) + 10h Size 32
Field Bit Attribute Default Description
UnitType 15:0 RO 16’b0

Unit type with which this PMON block is associated.

Each Unit of a Unit Type will have the same events available or capture and same protocol-specific performance monitoring HW available.

8’h00 = AXI4 in simple latency mode

8’h80 = AXI4 in advanced latency mode
UnitID 31:16 RO 16’b0

Which # of Unit Type

For cases where there are more than 1 instance of a particular Unit, this IDs the specific PMON block for the Unit Type. This value is passed in from the Unit ID parameter.
