— Universal asynchronous receiver transmitter (UART)
— Synchronous UART
— Serial infrared (IrDA)
— Binary synchronous communication (BISYNC)
— Totally transparent (bit streams)
— Totally transparent (frame based with optional cyclic redundancy check (CRC))
Two SMCs (serial management channels) (The MPC857DSL has one SMC, SMC1 for UART)
— UART
— Transparent
— General circuit interface (GCI) controller
— Can be connected to the time-division multiplexed (TDM) channels
One serial peripheral interface (SPI)
— Supports master and slave modes
— Supports multiple-master operation on the same bus
One inter-integrated circuit (I
— Supports master and slave modes
— Multiple-master environment support
Time-slot assigner (TSA) (The MPC857DSL does not have the TSA)
— Allows SCCs and SMCs to run in multiplexed and/or non-multiplexed operation
— Supports T1, CEPT, PCM highway, ISDN basic rate, ISDN primary rate, user defined
— 1- or 8-bit resolution
— Allows independent transmit and receive routing, frame synchronization, clocking
— Allows dynamic changes
— On the MPC862P and MPC862T, can be internally connected to six serial channels (four SCCs
Parallel interface port (PIP)
— Centronics interface support
— Supports fast connection between compatible ports on MPC862/857T/857DSL or MC68360
PCMCIA interface
— Master (socket) interface, release 2.1 compliant
— Supports one or two PCMCIA sockets dependent upon whether ESAR functionality is enabled
— 8 memory or I/O windows supported
Low power support
— Full on—All units fully powered
— Doze—Core functional units disabled except time base decrementer, PLL, memory controller,
and two SMCs); on the MPC857T, can be connected to three serial channels (one SCC and two
SMCs)
RTC, and CPM in low-power standby
