-1.0 Volts for a duration of 10 ns measured at the 50% amplitude points for Input-only lines (see Figure 5 on page 19).
Common I/O lines are clamped, so that signal transients can not fall below -0.5 Volts.
Over ambient operating temperature range and Vcc(min.) to Vcc(max.).
See Table 6 on page 15.
Control signals are /W, and /CM.
With load specified in Figure 4 on page 19, Test Load A.
With load specified in Figure 4 on page 19, Test Load B.
/E must be HIGH during this period to ensure accurate default values in the configuration registers.
With output and I/O pins unloaded.
