When a MTR_LCK event happens in this mode,
the status of external MOSFETs will be configured by MTR_LCK_MODE and nFAULT is driven low.
Status of external MOSFETs during MTR_LCK:
- MTR_LCK_MODE = 0000b or 0001b: All external MOSFETs are turned OFF, the
gate driver outputs pulled low.
- MTR_LCK_MODE = 0010b or 0011b: All low-side MOSFETs (gate driver outputs)
are turned ON.
The CONTROLLER_FAULT, MTR_LCK and respective motor lock condition bits are set to 1b in
the fault status registers. Normal operation resumes (gate driver operation and the nFAULT
pin is released) when the MTR_LCK condition clears and a clear fault command is issued
through the CLR_FLT bit.
