Table 4-65 R12 Register Field Descriptions
BitFieldTypeResetDescription
15I2C_ADDR_LSB_SELR/WL0x1

I2C peripheral address source. If this bit is a '1', SEPARATE_OE_EN must be '0'. This field is stored in the EFUSE.

0h: I2C peripheral address comes entirely from the I2C_ADDR field.

1h: The two lowest bits of the I2C peripheral address come from the FMT_ADDR pin, all other bits come from R12[14:10].

14:8I2C_ADDRR/WL0x68I2C peripheral address. After writing to this field, the device responds to the new I2C address. This field is stored in the EFUSE.
7:0UNLOCK_PROTECTED_REGR/W0x00

This field locks all registers from R13 onward, in addition to R12[15:8]. Registers R13 onward are largely device calibration registers, and must not have contents modified. These registers can be read from normally regardless of the unlock status.

5Bh: Unlocks register writes for R12[15:8] and above.

Any other value: R12[15:8] and above ignore all writes.
