to coprocessor 15, it is possible to transfer the coprocessor data to the coprocessor on
the IA and DA buses. To do this the coprocessor must drive GO on the coprocessor
shown in Figure 6-10.
Coprocessor 15 is typically reserved for use as a system control coprocessor. For an
handshake signals for a number of cycles. For each cycle that the coprocessor responds
with GO on the handshake signals, the coprocessor data is driven onto IA and DA as
