Cautions 1. V
SS functions alternately as the ground potential of the A/D converter. Be sure to connect VSS to
a stabilized GND (= 0 V).
2. Connect the REGC pin to V
SS via a capacitor (0.47 to 1 μ F).
3. ANI0/P20/AMP0-, ANI1/P21/AMP0OUT/PGAIN, ANI2/P22/AMP0+, and ANI3/P23 to ANI5/P25 are set
in the analog input mode after release of reset.
4. RESET/P125 immediately after release of reset is set in the external reset input.
