When a MTR_LCK event happens in this mode, the
status of MOSFETs will be configured by MTR_LCK_MODE and nFAULT is driven low.
Status of MOSFETs during MTR_LCK:
- MTR_LCK_MODE = 0000b or 0001b: All MOSFETs are turned OFF.
- MTR_LCK_MODE = 0010b: All high-side MOSFETs are turned ON.
- MTR_LCK_MODE = 0011b: All low-side MOSFETs 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.
