PRODUCTION DATA
#FAULT_STATUS_FAULT_STATUS_TABLE_1 lists the memory-mapped registers for the Fault_Status registers. All register offset addresses not listed in #FAULT_STATUS_FAULT_STATUS_TABLE_1 should be considered as reserved locations and the register contents should not be modified.
| Address | Acronym | Register Name | Section |
|---|---|---|---|
| E0h | GATE_DRIVER_FAULT_STATUS | Fault Status Register | #FAULT_STATUS_FAULT_STATUS_FAULT_STATUS_GATE_DRIVER_FAULT_STATUS |
| E2h | CONTROLLER_FAULT_STATUS | Fault Status Register | #FAULT_STATUS_FAULT_STATUS_FAULT_STATUS_CONTROLLER_FAULT_STATUS |
Complex bit access types are encoded to fit into small table cells. #FAULT_STATUS_FAULT_STATUS_LEGEND shows the codes that are used for access types in this section.
| Access Type | Code | Description |
|---|---|---|
