electrical ratings.
MOTOROLA
•
— Supports TC-layer and PMD-WIRE interface (according to the ATM-Forum af-phy-0063.000)
— Cell counters for performance monitoring
— Overrun (Rx cell FIFO) and underrun (Tx cell FIFO) condition produces maskable interrupt
— May be operated at E1 and DS-1 rates. In addition, xDSL applications at bit rates up to 10 Mbps
PCI bridge (MPC8265A and MPC8266A only)
— PCI Specification Revision 2.2 compliant and supports frequencies up to 66 MHz
— On-chip arbitration
— Support for PCI to 60x memory and 60x memory to PCI streaming
— PCI Host Bridge or Periphera
— Includes 4 DMA channels for the following transfers:
— Includes all of the configuration registers (which are automatically loaded from the EPROM
— Supports the I
— Hot-Swap friendly (supports the Hot Swap Specification as defined by PICMG 2.1 R1.0
— Support for 66 MHz, 3.3 V specification
— 60x-PCI bus core logic which uses a buffer pool to allocate buffers for each port
— Makes use of the local bus signals, so there is no need for additional pins
