Electrical and Thermal Characteristics
— Supports TC-layer and PMD-WIRE interface (according to the ATM-Forum af-phy-0063.000)
— Cell counters for performance monitoring
– 16-bit counters count
– HEC error cells
– HEC single bit error and corrected cells
– Idle/unassigned cells
fi
ltered
– Idle/unassigned cells transmitted
– Transmitted ATM cells
– Received ATM cells
– Maskable interrupt is sent to the host when a counter expires
— 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
are supported
PCI bridge (MPC8265A and MPC8266A only)
— PCI Speci

capabilities
— Includes 4 DMA channels for the following transfers:
– PCI-to-60x to 60x-to-PCI
– 60x-to-PCI to PCI-to-60x
– PCI-to-60x to PCI-to-60x
– 60x-to-PCI to 60x-to-PCI
— Includes all of the con
