Features
– Transparent
– UART (low-speed operation)
— One serial peripheral interface identical to the MPC860 SPI
— One inter-integrated circuit (I2C) controller (identical to the MPC860 I2C controller)
– Microwire compatible
– Multiple-master, single-master, and slave modes
— Up to eight TDM interfaces (four on the MPC8255)
– Supports two groups of four TDM channels for a total of eight TDMs
– 2,048 bytes of SI RAM
– Bit or byte resolution
– Independent transmit and receive routing, frame synchronization
– Supports T1, CEPT, T1/E1, T3/E3, pulse code modulation highway, ISDN basic rate, ISDN
primary rate, Freescale interchip digital link (IDL), general circuit interface (GCI), and
user-defined TDM serial interfaces
— Eight independent baud rate generators and 20 input clock pins for supplying clocks to FCCs,
SCCs, SMCs, and serial channels
— Four independent 16-bit timers that can be interconnected as two 32-bit timers
Additional features of the MPC826xA family are as follows:
CPM
— 32-Kbyte dual-port RAM
— Additional MCC host commands
— Eight transfer transmission convergence (TC) layers between the TDMs and FCC2 to support
inverse multiplexing for ATM capabilities (IMA) (MPC8264 and MPC8266 only)
CPM multiplexing
— FCC2 can also be connected to the TC layer.
TC layer (MPC8264 and MPC8266 only)
— Each of the 8 TDM channels is routed in hardware to a TC layer block
– Protocol-specific overhead bits may be discarded or routed to other controllers by the SI
– Performing ATM TC layer functions (according to ITU-T I.432)
– Transmit (Tx) updates
- Cell HEC generation
- Payload scrambling using self synchronizing scrambler (programmable by the user)
- Coset generation (programmable by the user)
- Cell rate by inserting idle/unassigned cells
– Receive (Rx) updates
- Cell delineation using bit by bit HEC checking and programmable ALPHA and DELTA
parameters for the delineation state machine
- Payload descrambling using self synchronizing scrambler (programmable by the user)
