System Clock
ADDR[23:0]
DATA[7:0]
Signal timing for Intel™ bus mode with multiplexed address and data is illustrated
for a Read operation in Figure 14 and for a Write operation in Figure 15. In these
figures, each Intel™ bus mode state is 2 CPU system clock cycles in duration.
Figures 14 and 15 also illustrate the assertion of one wait state (T
