24.7.4.3 Use Model 3: Connecting a Fabric AHB-Lite Master to the MSS Slave
The following figure shows the fabric AHB-Lite master connectivity with the MSS slaves and the AHB-Lite
slaves implemented in the fabric. An AHB-Lite fabric master can access memory mapped peripherals in
the MSS and AHB-Lite slaves in the fabric.

FPGA System with the MSS Slave and the Fabric Master
The following application note describes this Use Model with a design example:
SoC FPGA Dynamic Configuration of AHB Bus Matrix
. The design example consists of two AHB masters
in FPGA fabric that write 32-bit data to the AHB bus matrix slave eSRAM1.
