8.3.8. Interconnect Slave Properties
The interconnect connects to various slave interfaces through the L3 interconnect, L3 slave peripheral switch, and the five L4 peripheral buses. After reset, all slave interfaces are set to the secure state.
The interconnect provides FIFO buffers with clock crossing adapters. Refer to "FIFO Buffers and Clock Crossing" for details.
