mode
operation
In this mode, the analog inputs specified by the ADMn2 register are selected sequentially from the
ANIn0 pin using the ADTRGn signal as a trigger, and A/D converted. The A/D conversion results are
stored in the ADCRnm register corresponding to the analog input ANInm (n = 0, 1)(m = 0 to 9).
When conversion of all the specified analog inputs has ended, the A/D conversion end interrupt
(INTADn) is generated.n Unless the ADCE bit of the ADMn0 register is cleared to 0 after end of
conversion, the A/D converter waits for a trigger. The converter starts A/D conversion from the ANIn0
input when a trigger is input to the ADTRGn pin again.
Table 14-11:
Correspondence Between Analog Input Pins and ADCRnm Register
(External Trigger Scan)
When a trigger is input to the ADTRGn pin while the ADCEn bit of the ADMn0 register is 1, A/D
conversion is started again.
This is most appropriate for applications in which multiple analog inputs are constantly monitored.
