6.5. Soft Reset
The user may reset the circuit via SMBus by sending a general call address at slave address 0x00 followed by the reset
command 0x06. In other words, as illustrated in the figure below, a soft reset can be generated by sending a command at
slave address 0x00 (rather than the regular 0x4C slave address) to IC register address 0x06 with any data (0xXX).
The soft reset command sets the circuit and registers in the same state as after a power-up.
