Note
In the timer trigger mode (4-trigger mode) in the scan mode, because the scanning sequence of the
ANI0 to ANI3 pins is specified by the sequence in which the match signals are generated from the
compare register, the number of trigger inputs should be specified instead of specifying a certain
analog input pin. When ANIS2 = 1, perform conversion after shifting to A/D trigger scan mode,
which is possible after the trigger has been counted 4 times.
