Revision	Date	Description
A	02/2023	Remapping eNVM data from eNVM_1 memory block to Cortex®-M3 Code space is not permitted for SmartFusion® 2 M2S090/150 and IGLOO® 2 M2GL090/150 devices. For information about eNVM remapping and limitation, see the note under Figure 4-28. Timing models for Fabric to MSS interrupts have been updated with additional time delay. This changes the timing arcs of nets and interface between Fabric to MSS interrupts. For more information about the updated timing arcs, see PCN 17005A. Updated Embedded Trace Macrocell to include information about timing arcs update from Fabric to Embedded Trace Macrocell. Updated SGMII Interface Configuration to include information about timing arcs update from SerDes to Fabric. Updated Configuring the FIIC Using the Libero SoC to include information about timing arcs update from Fabric to MSS interrupts. The document was converted to Microchip template. The document number was changed to DS50003495 from UG0331.
