Internal Address Counter. The address of Z86E02 is
generated internally with a counter clocked through pin
P01 (Clock). Each clock signal increases the address by
one and the "high" level of pin P00 (Clear) will reset the ad-
dress to zero. Figure 19 shows the setup time of the serial
address input.
Programming Waveform. Figures 20, 21, 22, and 23
show the programming waveforms of each mode. Table 7
shows the timing of programming waveforms.
Programming Algorithm. Figure 24 shows the flow chart
of the Z86E02 programming algorithm.
