*(1), 11001: AIN13*(2),

11010: AIN14

*(3), others: Reserved.

*(1) AIN12 channel is OP0-Amp output terminal.

*(2) AIN13 channel is OP1-Amp output terminal.

*(3) The AIN14 is internal 2V or 3V or 4V input channel. There is no any input pin from outside. In this time ADC

reference voltage must be internal VDD and External voltage, not internal 2V or 3V or 4V.
