MC68EC030 TECHNICAL DATA

ACCESS CONTROL
Two access control registers are provided on the MC68EC030 to control cachability of accesses for two
independent blocks of memory. Each block can range in size from 16 Mbytes to 2 Gbytes, and is
specified in the corresponding ACx register with a base address, a base mask, function code, function
code mask, and read/write mask. A typical use for an access control register is to designate a block of
memory containing I/O devices as non-cachable.
COPROCESSOR INTERFACE
The coprocessor interface is a mechanism for extending the instruction set of the M68000 Family. The
interface provided on the MC68EC030 is the same as that on the MC68020 and MC68030. Examples of
these extensions are the addition of specialized data operands for the existing data types or, for the case
of
floating
point,
the
inclusion
of
new
data
types
and
operations
implemented
by
the
MC68881/MC68882 floating-point coprocessors.
