Table A-2 Coprocessor interface signals (continued)
Description
The handshake signals from the Execute stage of the
coprocessors pipeline follower. Indicates ABSENT
(10), WAIT (00), GO (01), or LAST (11). If no
external coprocessors are attached these must be tied
to b10 (ABSENT response).
Valid instruction indicator for CPINSTR (replaces
CPTBIT).
If this signal is LOW on the rising edge of CLK and
CPCLKEN is HIGH, the instruction on CPINSTR
must enter the coprocessor pipeline.
When LOW the coprocessor interface is in a
nonprivileged state. When HIGH the coprocessor
interface is in a privileged state.
