HiZ management
L6740L is able to manage HiZ through both the PWMx and driver enable signals. When the
controller wants to set in high impedance the output of one section, it set the relative PWM
floating and, at the same time, pulls-low the related ENDRV.
Hardware jumper override - V_FIX
Anytime the pin OVP/V_FIX is driven low, the controller enters V_FIX mode.
When in V_FIX mode, both NB and CORE section voltages are governed by the information
shown in
and SVD are considered as static VID and the output voltage will change according to their
status. Dynamic SVC/SVD-change management is provided in this condition.
V_FIX mode is intended for system debug only.
Protection management differs in this case, see

No strategy.
PSI_L still reproduces the status of the PSI Flag
Phase number is cut by 1 while PSI_L is asserted.
Phase number is cut by 2 while PSI_L is asserted.
