2.4.2 OTG Function

Use the following for OTG function settings:

1. Set EN_OTG high on J2 (EN_OTG) or short TP37 to TP35 (EN_OTG).
2. Connect a 7-V power supply to the VBAT load. Remove the V_IN power supply from J1. (Connection must be physically removed from board).
3. Write the Charge Voltage Register to 0x20D0.
4. Write “0200” to the OTG voltage register. Write “4000” to the OTG current registers.
5. Select EN_OTG in Charge Option 3.
   Measure → V(J1(V_IN)) = 5 V ±1 V
