ADVANCE
Melody Routing Coprocessor
1
-1.0V for a duration of 10ns measured from the 50 percent amplitude points (see Figure 5 on page 25) for input-only
lines
2
Common I/O lines are clamped so that transients cannot fall below -0.5V
3
Applies to all cycle types except Compare cycles and Memory Read cycles (memory to DQ)
4
Applies to Compare cycles (including NEXT)
5
Control signals are CS#1, CS#2, W#, AV#, DSC, and the AC bus
6
With loads specified in Figure 4 on page 25, Test load A from Table 8
7
With loads specified in Figure 4 on page 25, Test load B from Table 8
8
E# should be HIGH during RESET# active to ensure proper device defaults
9
Test inputs are the TDI and TMS signals
10 With output and I/O pins unloaded
11 Pins with internal pull-ups are RESET#, TCLK, TMS, TDI, and TRST#
