The functional blocks of SEROCCO-H can be divided into two major domains:
– the microprocessor interface of SEROCCO-H provides access to on-chip registers
– the Serial Communication Controller (SCC) is capable of processing bit-synchronous
Data exchange between the serial communication controller and the microprocessor
interface is performed using FIFOs, decoupling these two domains.

and to the "user" portion of the receive and transmit FIFOs (RFIFO/XFIFO). Optionally
these FIFOs can be accessed by an external 4-channel DMA controller.
(HDLC/SDLC/bitsync PPP) and octet-synchronous (octet-sync PPP) as well as fully
transparent data traffic.
