1.0 Volts for a duration of 10 ns measured at the 50% amplitude points for Input-only lines (see Figure 11 on page 27).
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 23.
Control signals are /W, /CM, and /EC.
With load specified in Figure 10 on page 27, Test Load A.
With load specified in Figure 10 on page 27, 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.
