Leave R32 and
R33 unpopulated

Note
Liquid Detection/Corrosion Mitigation and BC1.2 cannot be configured in the same system, so make
sure R32/R33 and R34/R36 are not both populated at the same time.
On the TPS25751EVM the hardware is set to use specific GPIOs for MOSFET control and Liquid Detection
feature. For user applications, some GPIOs can be configured differently while some are required for all designs,
refer to Table 4-3 for details on specific test point and the configurability for custom designs. Refer to Section
4.3.2.
