If ADI = 0 in IOCE PAGE0 Bit5, when A/D start conversion by setting ADST(IOCB PAGE1 Bit0) = 1 then
A/D will continue conversion without stop and hardware won’t reset ADST bit. In this condition, ADI is
deactived. After ADI in IOCE PAGE0 bit5 is set, ADI in RE PAGE0 bit5 will activate again.
To minimum operating current , all biasing circuits in the A/D module that consume DC current are power
down when ADPWR bit in IOCB PAGE1 Bit2 register is a ’0’. When ADPWR bit is a ‘1’, A/D converter
module is operating.
User has to set PORT60~ PORT65as AD converter input pin or bi-direction IO PORT.
