The MSMC has the following registers for interrupt control:
Each bit in these registers represents a single event or interrupt supported by MSMC, which generates only one interrupt. This is the null slave error interrupt (MSMC_NULL_SLAVE_ERROR). MSMC sets this event when routing a command through the MSMC null slave port which results in an unsuccessful response status. Commands failing firewall checks do not trigger the null slave error interrupt event in MSMC.
