Coprocessor 15 is typically reserved for use as a system control coprocessor. For an
MCR 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 should drive GO on the coprocessor
handshake signals for a number of cycles. For each cycle that the coprocessor
responded with GO on the handshake signals the coprocessor data will be driven onto
IA and DA as shown in Figure 4-8.
