Part I. Overview
¥ Two SMCs (serial management channels)
Ñ UART
Ñ Transparent
Ñ General circuit interface (GCI) controller
Ñ Can be connected to the time-division multiplexed (TDM) channels
¥ One SPI (serial peripheral interface)
Ñ Supports master and slave modes
Ñ Supports multimaster operation on the same bus
2
¥ One I C (inter-integrated circuit) port
Ñ Supports master and slave modes
Ñ Multiple-master environment support
¥ Time-slot assigner (TSA)
Ñ Allows SCCs and SMCs to run in multiplexed and/or non-multiplexed operation
Ñ Supports T1, CEPT, PCM highway, ISDN basic rate, ISDN primary rate, user
deÞned
Ñ 1- or 8-bit resolution
Ñ Allows independent transmit and receive routing, frame synchronization,
clocking
Ñ Allows dynamic changes
Ñ Can be internally connected to six serial channels (four SCCs and two SMCs)
¥ Parallel interface port (PIP)
Ñ Centronics interface support
Ñ Supports fast connection between compatible ports on MPC860 or MC68360
¥ PCMCIA interface
Ñ Master (socket) interface, release 2.1 compliant
Ñ Supports two independent PCMCIA sockets
Ñ 8 memory or I/O windows supported
¥ Low power support
Ñ Full onÑAll units fully powered
Ñ DozeÑCore functional units disabled except time base decrementer, PLL,
memory controller, RTC, and CPM in low-power standby
Ñ SleepÑAll units disabled except RTC, PIT, time base, and decrementer with
PLL active for fast wake up
Ñ Deep sleepÑAll units disabled including PLL except RTC, PIT, time base, and
decrementer.
Ñ Power down modeÑ All units powered down except PLL, RTC, PIT, time base
and decrementer
