Control register  PCA9547PW,118

Following the successful acknowledgement of the slave address, the bus master will send

a byte to the PCA9547, which will be stored in the Control register. If multiple bytes are

received by the PCA9547, it will save the last byte received. This register can be written

and read via the I2C-bus.
