Introduction

The SEROCCO-M is a Serial Communication Controller with two independent serial

channels1). The serial channels are derived from updated protocol logic of the ESCC and

DSCC4 device family providing a large set of protocol support and variety in serial

interface configuration. This allows easy integration to different environments and

applications.

A generic 8- or 16-bit multiplexed/demultiplexed slave interface provides fast device

access with low bus utilization and easy software handshaking. DMA handshake control

signals allow connection to an external DMA controller.

Large on-chip FIFOs of 64 byte capacity per port and direction in combination with

enhanced threshold control mechanisms allow decoupling of traffic requirements on host

bus and serial interfaces with little exception probabilities such as data underruns or

overflows.

Each of the two Serial Communication Controllers (SCC) contains an independent Baud

Rate Generator, DPLL and programmable protocol processing (HDLC, PPP, ASYNC

and BISYNC). Data rates of up to 16 Mbit/s (HDLC, PPP, bit transparent) and 2 Mbit/s

(DPLL assisted modes) are supported. The channels can also handle a large set of

layer-2 protocol functions (LAPD, SS7) reducing bus and host CPU load. Two channel

specific timers are provided to support protocol functions.

1) The serial channels are also called ’ports’ or ’cores’ depending on the context.
