Features

— Allows dynamic changes

— Can be internally connected to six serial channels (four SCCs and two SMCs)

•

Parallel interface port (PIP)

— Centronics interface support

— Supports fast connection between compatible ports on the MPC860 or the MC68360

•

PCMCIA interface

— Master (socket) interface, release 2.1 compliant

— Supports two independent PCMCIA sockets

— Supports eight memory or I/O windows

•

Low power support

— Full on—all units fully powered

— Doze—core functional units disabled except time base decrementer, PLL, memory controller,

RTC, and CPM in low-power standby

— Sleep—all units disabled except RTC and PIT, PLL active for fast wake up

— Deep sleep—all units disabled including PLL except RTC and PIT

— Power down mode—all units powered down except PLL, RTC, PIT, time base, and

decrementer

•

Debug interface

— Eight comparators: four operate on instruction address, two operate on data address, and two

operate on data

— Supports conditions: =

≠ <>

— Each watchpoint can generate a break-point internally.
