-1.0 Volts for a duration of 10 ns measured at the 50% amplitude points for Input-only lines (see Figure 7 on page 29).
Common I/O lines are clamped, so that signal transients can not fall below -0.5 Volts.
Applies to all cycle types except Compare cycles and Memory Read cycles (memory to DQ).
Applies to Compare cycle (including NEXT).
Control signals are /CS1, /CS2, /W, /AV, DSC, and the AC bus.
With load specified in Figure 6 on page 29, Test Load A from Table 7.
With load specified in Figure 6 on page 29, Test Load B from Table 7.
/E should be HIGH during /RESET active to ensure proper device defaults.
Test inputs are TDI and TMS signals.
Pins with internal pull-ups are /RESET, TCLK, TMS, TDI, and /TRST.
