18.6 Memory Cycle Variables

The timing tables below use three variables which are derived from registers SY-

SCON and BUSCON1 and represent the special characteristics of the programmed

memory cycle. The following table describes, how these variables are to be comput-

ed.

AC inputs during testing are driven at 2.4 V for a logic ‘1’ and 0.4 V for a logic ‘0’.

Timing measurements are made at V

IH min for a logic ‘1’ and VIL max for a logic ‘0’.

For timing purposes a port pin is no longer floating when a 100 mV change from load

voltage occurs, but begins to float when a100 mV change from the loaded V

OH/VOL level occurs

OH/IOL = 20 mA).
