CAUTION

If wanting to run TPS23882B1 in semi-auto mode, remove the jumper installed on J5 of the
TPS23882B1 daughterboard before powering on the board.

CAUTION

Do not press the RESET button (S1) on the motherboard while communicating over I2C. Pressing
this button will set all ports to off mode and the reference code will not be able to recover.
