1 DO goes low when I-1 changes. *

However, if I/O-1 and I/O-2 are set to output mode, they go to the open state.

Note: 2. Invalid if the I/O-5 pin is set to input mode.

Caution: Cannot be used in crystal oscillator stop mode (The DO pin will not change state.)

[When the reference divider data is R3 = R2 = R1 = 1, and R0 = 0.]

If both the ADC0 and ADC1 pins are specified as A/D converter inputs, the levels are

converted sequentially in the order ADC0 first and the ADC1. See the “A/D Converter

Structure” item for details.
