Indicates
stage of coprocessor pipeline.
attached, this must be tied to b0000.
Coprocessor clock enable. When HIGH on the rising
edge of CLK the pipeline follower logic can
advance.
The coprocessor data bus for transferring data from
the coprocessor.
The coprocessor data bus for transferring data to the
coprocessor.
When LOW disables the external coprocessor
interface. If CPEN is LOW then CHSDE and
CHSEX must both be driven to b10 (ABSENT
response).
The coprocessor instruction bus that instructions are
transferred over to the pipeline follower in the
coprocessor.
Indicates that there is a coprocessor instruction in the
Execute stage of the pipeline, that must be executed.
If HIGH during the first Memory cycle of a
coprocessor instruction, then the coprocessor must
cancel the instruction without changing any internal
state.
The handshake signals from the Decode stage of the
coprocessor pipeline follower. Indicates ABSENT
(b10), WAIT (b00), GO (b01), or LAST (b11). If no
external coprocessors are attached this must be tied to
b10 (ABSENT response).
Indicates number of words to be transferred for
