... POWER-ON RESET When power is applied to V PCA9555 in a reset condition until V point, the reset condition is released and the PCA9555 registers and SMBus state machine will initialize to their default states. The power-on reset typically completes the reset and enables the part by the time the power supply is above V required to reset the part by lowering the power supply necessary to lower it below 0 ...

... Sep 30 Reading the port registers In order to read data from the PCA9555, the bus master must first send the PCA9555 address with the least significant bit set to a logic 0 (see Figure 5 for device address). The command byte is sent after the address and determines which register will be accessed ...
