Freescale Semiconductor
Features
System integration unit (SIU)
— Bus monitor
— Software watchdog
— Periodic interrupt timer (PIT)
— Low-power stop mode
— Clock synthesizer
— Decrementer, time base, and real-time clock (RTC)
— Reset controller
— IEEE 1149.1 Std. test access port (JTAG)
Interrupts
— Seven external interrupt request (IRQ) lines
— 12 port pins with interrupt capability
— 23 internal interrupt sources
— Programmable priority between SCCs
— Programmable highest priority request
10/100 Mbps Ethernet support, fully compliant with the IEEE 802.3u Standard (not available
when using ATM over UTOPIA interface)
ATM support compliant with ATM forum UNI 4.0 specification
— Cell processing up to 50–70 Mbps at 50-MHz system clock
— Cell multiplexing/demultiplexing
— Support of AAL5 and AAL0 protocols on a per-VC basis. AAL0 support enables OAM and
software implementation of other protocols.
— ATM pace control (APC) scheduler, providing direct support for constant bit rate (CBR) and
unspecified bit rate (UBR) and providing control mechanisms enabling software support of
available bit rate (ABR)
— Physical interface support for UTOPIA (10/100-Mbps is not supported with this interface) and
byte-aligned serial (for example, T1/E1/ADSL)
— UTOPIA-mode ATM supports level-1 master with cell-level handshake, multi-PHY (up to four
physical layer devices), connection to 25-, 51-, or 155-Mbps framers, and UTOPIA/system
clock ratios of 1/2 or 1/3.
— Serial-mode ATM connection supports transmission convergence (TC) function for
T1/E1/ADSL lines, cell delineation, cell payload scrambling/descrambling, automatic
idle/unassigned cell insertion/stripping, header error control (HEC) generation, checking, and
statistics.
Communications processor module (CPM)
— RISC communications processor (CP)
— Communication-specific commands (for example, GRACEFUL STOP TRANSMIT, ENTER HUNT
MODE
, and RESTART TRANSMIT)
— Supports continuous mode transmission and reception on all serial channels
