*1 : At FCP = 16 MHz, tSMP = 32 × tCP = 2.000 (µs) .
*2 : At FCP = 16 MHz, tCMP = 66 × tCP = 4.125 (µs) .
*3 : Equivalent to conversion time per channel at FCP = 16 MHz, and selection of tSMP = 32 × tCP and tCMP = 32 × tCP.
*4 : Defined as supply current (when VCC = AVCC = AVRH = 5.0 V) with A/D converter not operating, and CPU in
stop mode.
