PRELIMINARY - 6/15/93

AC Electrical Characteristics

— Reset, Stop, Wait, Mode Select, and Interrupt Timing

(Vdd = 5.0 Vdc +/- 10%, TJ = -40 to +125 °C, CL = 50 pF + 1 TTL Load).

cyc = Clock cycle = 1/2 instruction cycle = 2 T cycles

ws= Number of wait states programmed into external bus access using BCR (WS = 0 - 31)
