9.4.1 RESET Input

The RESET input can be used to recover the TCA9545A from a bus-fault condition. The registers and the I2C state machine within this device initialize to their default states if this signal is asserted low for a minimum of tWL. All channels also are deselected in this case. RESET must be connected to VCC through a pull-up resistor.
