SNVSB64A June 2019 – June 2021 LP8733-Q1
PRODUCTION DATA
The LP8733xx-Q1 is controlled by a set of registers through the I2C-compatible interface. The device registers addresses and abbreviations are listed in Table 7-7. A more detailed description is given in the Section 7.6.1.1 to Section 7.6.1.39 sections.
This register map describes the default values for bits that are not read from OTP memory. The orderable code and the default register bit values are defined in part-number specific Technical Reference Manuals.
