36.5.15 I2CxADR1
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.
