6.7.4 Gate_Driver_Configuration Registers

Table 6-34 lists the memory-mapped registers for the Gate_Driver_Configuration registers. All register offset addresses not listed in Table 6-34 should be considered as reserved locations and the register contents should not be modified.

Table 6-34 GATE_DRIVER_CONFIGURATION Registers

Offset	Acronym	Register Name	Section
ACh	GD_CONFIG1	Gate driver configuration 1	Section 6.7.4.1
AEh	GD_CONFIG2	Gate driver configuration 2	Section 6.7.4.2

Complex bit access types are encoded to fit into small table cells. Table 6-35 shows the codes that are used for access types in this section.
