When a LOCK_ILIMIT event happens in this mode, the
status of MOSFETs will be configured by LOCK_ILIMIT_MODE and nFAULT is driven low.
Status of MOSFETs during LOCK_ILIMIT:
- LOCK_ILIMIT_MODE = 0000b: All
MOSFETs are turned OFF.
- LOCK_ILIMIT_MODE = 0001b: MOSFET which was switching is
turned OFF while the one which was conducting stays ON till inductive energy
is completely recirculated.
- LOCK_ILIMIT_MODE = 0010b: All
high-side MOSFETs are turned ON.
- LOCK_ILIMIT_MODE = 0011b: All
low-side MOSFETs are turned ON.
The CONTROLLER_FAULT and LOCK_ILIMIT bits are set to 1b in the fault status
registers. Normal operation resumes (gate driver operation and the nFAULT pin is
released) when the LOCK_ILIMIT condition clears and a clear fault command is issued
through the CLR_FLT bit.
