When a LOCK_ILIMIT event happens in
this mode, the status of external MOSFETs will be configured by LOCK_ILIMIT_MODE and
nFAULT is driven low. Status of external MOSFETs driven from MCF8329HS-Q1 during LOCK_ILIMIT:
- MTR_LCK_MODE = 000b: All
external MOSFETs are turned OFF, the gate driver outputs pulled low.
- MTR_LCK_MODE = 001b or 010b:
All low-side MOSFETs (gate driver outputs) 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.
