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 MCF8329A-Q1 during LOCK_ILIMIT:
- LOCK_ILIMIT_MODE = 0000b or
0001b: All MOSFETs are turned OFF, the gate driver outputs pulled low.
- LOCK_ILIMIT_MODE = 0010b or
0011b: 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.
