(1) Trigger mode
There are two types of trigger modes that serve as the start timing of an A/D conversion operation: software
trigger mode and hardware trigger mode. There are two types of hardware trigger modes: external trigger
mode and timer trigger mode.
These trigger modes are set by the ADAnM0 and ADAnM2 registers.
Remark
(a) Software trigger mode
Of the ANIn0 to ANIn3 pins, the analog input pin specified by the ADAnS.ADAnS1 and ADAnS.ADAnS0
bits is used for the A/D conversion start timing when the ADAnM0.ADAnCE bit is set to 1 in this mode.
After end of A/D conversion, the conversion result is stored in A/Dn conversion result register m
(ADAnCRm) (m = 0 to 3). At the same time, an A/Dn conversion end interrupt request signal (INTADn) is
generated.
If the operation mode set by the ADAnM0.ADAnMD1 and ADAnM0.ADAnMD0 bits is the continuous select
mode or continuous scan mode, the conversion operation is repeated unless the ADAnM0.ADAnCE bit is
cleared to 0. In the one-shot select mode or one-shot scan mode, the conversion operation is stopped
after A/D conversion ends.
When conversion is started, the ADAnM0.ADAnEF bit is set to 1 (conversion in progress).
If the ADAnM0, ADAnM2, and ADAnS registers are written during A/D conversion, the conversion is
stopped and executed again from the beginning.
