FUNCTIONAL DESCRIPTION
(Continued)
Internal Address Counter.
The address of Z86E04/E08
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 18 shows the setup time of the serial
address input.
Programming Waveform.
Figures 19, 20 and 21 show
the programming waveforms of each mode. Table 8 shows
the timing of programming waveforms.
Programming Algorithm.
Figure 22 shows the flow chart
of the Z86E04/E08 programming algorithm.
