8.1 Fault_Status Registers

Table 8-1 lists the memory-mapped registers for the Fault_Status registers. All register offset addresses not listed in Table 8-1 should be considered as reserved locations and the register contents should not be modified.

Table 8-1 FAULT_STATUS Registers

Offset	Acronym	Register Name	Section
E0h	GATE_DRIVER_FAULT_STATUS	Fault Status Register	Section 8.1.1
E2h	CONTROLLER_FAULT_STATUS	Fault Status Register	Section 8.1.2

Complex bit access types are encoded to fit into small table cells. Table 8-2 shows the codes that are used for access types in this section.

Table 8-2 Fault_Status Access Type Codes

Access Type	Code	Description

-n		Value after reset or the default value

8.1.1 GATE_DRIVER_FAULT_STATUS Register (Offset = E0h) [Reset = 00000000h]

GATE_DRIVER_FAULT_STATUS is shown in Figure 8-1 and described in Table 8-3.
