Chapter 14A/D ConverterXIV - 32 Operation■ Multiple Channels/Continuous Conversion (AD0, AD1)Continuous multiple A/D input is converted continuously. The A/D interrupt is generated every time all conver-sions of multiple channels end. Set the first channel to be converted by the ANnCH2-0 flags of the ANnCTR0and the last channel by the ANnNCH2-0 flags of the ANnCTR1 register.When conversion is started by the ANnEN flag (conversion start-execution flag), set the ANnTRG flag to “0” andthe ANnEN flag to “1”. Conversion is terminated by setting the ANnEN flag to”0” forcedly. The ANnEN flag is“1” during conversion and changes to “0” after conversion of all channels end. The AN2CH3-0 flags become thechannel number being converted during conversion and change to the first channel number after conversion of allchannels is completed.■ Multiple Channels/Continuous Conversion (AD2)Continuous multiple A/D input is converted continuously.
