The logic is controlling the correct sequence in closing the
switches and in interpreting the 32 m s debounced
HW2_Cmp output accordingly. The output of this small
state ? machine is corresponding to:
? High or address = 1
? Low or address = 0
? Floating
As illustrated in the table above (Table 15), the state is
depending on the previous state, the condition of the 2
switch controls (DriveLS and DriveHS) and the output of
HW2_Cmp. The figure below is showing an example of a
practical case where a connection to VBAT is interrupted.
