PRODUCTION DATA.
The DSEL pin is normally grounded and pulled-up by internally to 5V during input source type detection (when AUTO_DPDM_EN=1 or FORCE_DPDM=1). The pin is normally low and drives high to indicate the D+/D- detection is in progress. When detection is completed, the pin maintains high logic when DCP, MaxCharge or HVDCP is detected. The pin returns to logic low when other input source type is detected. In addition, while input source is plugged in or during OTG mode, the FORCE_DSEL bit can be set to force the DSEL pin to change from low to high regardless of input source type detected. When in battery discharge mode (not in OTG), the DSEL pin is always low.
