2 – MSS Configuration Guidelines Although the MSS configurator allows you to configure all sub-blocks out of order, Microsemi recommends that you configure the various sub-blocks in a particular order as the configuration of some sub-blocks depends on others. Configure the MSS sub-blocks in the following order: 1. External Memory Configuration (MDDR sub-block) 2. Fabric Interface Controller (FIC32_0 and FIC32_1 sub-blocks) 3.
