Fault/Status Registers
The following tables describe the 24 bits within the Fault/Status Registers. When Bit 7 of Register 0x04 (Slave
address 1001) is low, then the data within these registers represents the real-time state of the part. When Bit 7 is
high, then these registers represent data that was latched at the time that the Fault occurred. There are three
Status/Fault Registers, accessed at slave address 1001 with address bit A8 set low, at word address 0x02-0x04.
