P3_OUT_CTRL
1 = P3_x port output is powered by the 1 V rail
0 = P3_x port output is powered by the 3 V rail
bit 0 controls the power of P3[0],
bit 7 controls the power of P3[7],
(Note 6)
Note 6: In Buck mode the output must be powered by the 3 V rail. In Boost mode the outputs can be powered by the 1 V rail or by the 3 V rail. In
Boost mode the 3 V rail can only supply a limited current, e.g. for switching a high-impedance input of an external device. See table 'Digital
input/output characteristics'.
