(2) Default condition
(3) Setting the P5SEL.0 bit disables the output driver as well as the input Schmitt trigger to prevent parasitic cross currents when applying
analog signals. An external voltage can be applied to VeREF+ and used as the reference for the ADC12_A, Comparator_B, or
DAC12_A.
(4) Setting the P5SEL.0 bit disables the output driver as well as the input Schmitt trigger to prevent parasitic cross currents when applying
analog signals. The ADC12_A, VREF+ reference is available at the pin.
(5) Setting the P5SEL.1 bit disables the output driver as well as the input Schmitt trigger to prevent parasitic cross currents when applying
analog signals. An external voltage can be applied to VeREF- and used as the reference for the ADC12_A, Comparator_B, or
DAC12_A.
(6) Setting the P5SEL.1 bit disables the output driver as well as the input Schmitt trigger to prevent parasitic cross currents when applying
analog signals. The ADC12_A, VREF– reference is available at the pin.
