The MCU (S32K344) sends the data: 0xA2 0x04. Where: 0xA2 is composed of the device ID: 0x51 and writeBit. After sending the first byte, the PCA85073A does not send the ACK bits causing the MCU to stop sending.
I2C-SCL and I2C_SDA are connected with 3K up resistance.VCC=4.75V。
Why did the PCA85073A not respond to the ACK?
