ZHCSNJ4B September 2007 – March 2021 PCA9543A
PRODUCTION DATA
Following the successful acknowledgment of the slave address, the bus master sends a byte to the PCA9543A, which is stored in the control register (see Figure 8-8). If multiple bytes are received by the PCA9543A, it saves the last byte received. This register can be written and read via the I2C bus.
