NOTES: A. RS forces DEN, WE, and MEN high and places data bus D0 through D15 in a high-impedance state. AB outputs (and program count-
er) are synchronously cleared to zero after the next complete CLK cycle from RS
.
B. RS must be maintained for a minimum of five clock cycles.
C. Resumption of normal program will commence after one complete CLK cycle from RS
.
D. Due to the synchronization action on RS, time to execute the function can vary dependent upon when RS
or RS
occur in the CLK
cycle.
E. Diagram shown is for definition purpose only. DEN, WE, and MEN are mutually exclusive.
F. During a write cycle, RS may produce an invalid write address.
