•
— Two serial management controllers (SMCs), identical to those of the MPC860
— One serial peripheral interface identical to the MPC860 SPI
— One I
— Up to two TDM interfaces
— Eight independent baud rate generators and 14 input clock pins for supplying clocks to FCC,
— Four independent 16-bit timers that can be interconnected as two 32-bit timers
PCI bridge
— 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 peripheral capabilities
— Includes four DMA channels for the following transfers:
— Includes the configuration registers required by the PCI standard (which are automatically
— Supports the I
— Hot-Swap friendly (supports the Hot Swap Specification as defined by PICMG 2.1 R1.0 August
— Support for 66-MHz, 3.3-V specification
— 60x-PCI bus core logic, which uses a buffer pool to allocate buffers for each port

time-division-multiplexed (TDM) channels
• Compatible with T1/DS1 24-channel and CEPT E1 32-channel PCM highway, ISDN
• Subchanneling on each time slot.
• Independent transmit and receive routing, frame synchronization and clocking
• Concatenation of any not necessarily consecutive time slots to channels independently
• Supports H1,H11, and H12 channels
• Allows dynamic allocation of channels
