Fault Register
The Fault Register is a read only register that shows the fault number under the current sensor conditions. Any write to the Fault
Register will clear the register, when in Stop mode. The Fault register cannot be cleared when the part is in a Run mode. The I2C
slave address of the Fault Register is 0x01.
