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
F).
3. ANI0/P20/AMP-, ANI1/P21/AMPOUT/PGAIN, ANI2/P22/AMP+, ANI3/P23/CMP2+, ANI4/P24/CMP0+,
and ANI5/P25/CMP1+ 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.
Remark Functions in angle brackets < > can be assigned by setting the input switch control register (MUXSEL).
