In the external trigger mode, the analog input pins (ANIn0 to ANIn3)
The ADTRG0 pin has an alternate function as the P04/INTP4 pin and the ADTRG1 pin has an alternate function as

When the ADAnM0.ADAnCE bit is set (1), the A/D converter waits for a trigger and, when the trigger is input from
After the end of A/D conversion, the conversion result is stored in A/Dn conversion result register m (ADAnCRm)
After the end of A/D conversion, the A/D converter waits for a trigger regardless of the operation mode set by the
When conversion is started, the ADAnM0.ADAnEF bit is set to 1 (conversion in progress). However, while the A/D
If a valid trigger is input during A/D conversion, the conversion operation is stopped and started again from the
Note Only the ANI00 and ANI01 pins can be used when A/D converter 0 of the V850E/IA3 is used.
