37.5.20 I2CxADR3

I2C Address 3 Register⁽¹⁾

Note:

The ‘11110’ bit pattern used in the 10-bit address high byte is defined by the I²C Specification. It is up to the user to define these bits. These bit values are compared to the received address by hardware to determine a match. The bit pattern transmitted by the host must be the same as the client address’s bit pattern used for comparison or a match will not occur.
