PRODUCTION DATA
#GUID-20220906-SS0T-66SF-MJTL-K7G1PDSBMVQR/FAULT_STATUS_FAULT_STATUS_TABLE_1_TABLE lists the memory-mapped registers for the Fault_Status registers. All register offset addresses not listed in #GUID-20220906-SS0T-66SF-MJTL-K7G1PDSBMVQR/FAULT_STATUS_FAULT_STATUS_TABLE_1_TABLE should be considered as reserved locations and the register contents should not be modified.
Offset | Acronym | Register Name | Section |
---|---|---|---|
E0h | GATE_DRIVER_FAULT_STATUS | Fault Status Register | GATE_DRIVER_FAULT_STATUS Register (Offset = E0h) [Reset = 00000000h] |
E2h | CONTROLLER_FAULT_STATUS | Fault Status Register | CONTROLLER_FAULT_STATUS Register (Offset = E2h) [Reset = 00000000h] |
Complex bit access types are encoded to fit into small table cells. #GUID-20220906-SS0T-66SF-MJTL-K7G1PDSBMVQR/FAULT_STATUS_FAULT_STATUS_LEGEND_TABLE shows the codes that are used for access types in this section.
