Note: * Continuous scan mode or single-scan mode can be selected with the ADCS bit.
When 2-, 4-, or 8-channel scan mode has been selected, the channels for operation are
selected only by bits CH2 to CH0. For example, when 8-channel scan mode has been
selected with continuous scan mode, continuous conversion will be performed on AN8 if
bits CH2 to CH0 have been set to 000.
