21 / 86 page ![]() Page 20 Datasheet, Public Document Feedback [v2-00] 2022-Nov-03 TMD4903 − Register Description The device is controlled and monitored by registers accessed through the I²C serial interface. These registers provide for a variety of control functions and can be read to determine results of the ADC conversions. The register set is summarized in Figure 25.
