1.4
This chapter is useful for all being familiar with the HSCX/ESCC family.
1.4.1
The SEROCCO-H SCC cores contain the core logic of the HSCX as the heart of the
device. Some enhancements are incorporated in the SCCs. These are:
• Octet- and Bit Synchronous PPP protocol support as in RFC-1662
• Signaling System #7 (SS7) support
• 4-kByte packet length byte counter
• Enhanced address filtering (16-bit maskable)
• Enhanced time slot assigner
• Support of high data rates (12.5 Mbit/s)
1.4.2
The following features of the HSCX core have been removed:
• Extended transparent mode 0
• Master clock mode
Data Sheet
(this mode provided octet buffered data reception without usage of FIFOs;
SEROCCO-H supports octet buffered reception via appropriate threshold
configurations for the SCC receive FIFOs)
