The functional blocks of the DSCC4 can be partitioned into three different groups:
– The first group provides the data transfer between the shared memory and on chip
– The second group supports the multiport and multiprotocol serial data communication.
– The third group provides control functions for external peripherals using the LBI and/

registers/FIFOs. It consists of the PCI System Bus Interface, the 9 DMACs, the
Central RFIFO, the Central TFIFO and the Central Interrupt Queue.
It consists of four SCCs.
