Contention between Buffer Register Write and Compare Match in Buffer Operation: If a
compare match occurs in the T2 state of a buffer register write cycle, the old data (before being
updated) in the buffer register is transferred to the general data in a buffer operation. Figure 12.36
shows this timing.
