VTF Logic
Figure 2.21-1 shows the logics of the VTF function. As described earlier, the VT failure is
grouped into the VTF1 criterion (VTF1_DETECT) and the VTF2 criterion (VTF2_DETECT).
When we consider the VTF1 criterion, the upper logic in Figure 2.21-1 is used; whereas we
consider the VTF2 criterion, lower one is used.
The user can select either the VTF1 or VTF2 criteria using the using the scheme switch
[
VTF1EN
] or [
VTF2EN
].
