4-buffer mode (external trigger select: 4 buffers)
In this mode, one analog input is A/D converted four times using the ADTRGn signal as a trigger
and the results are stored in the ADCRnm register. The A/D conversion end interrupt (INTADn) is
generated and A/D conversion is stopped after the 4th A/D conversion.
Table 14-10:
Correspondence Between Analog Input Pins and ADCRnm Register
(External Trigger Select: 4 Buffers))
While the ADCEn bit of the ADMn0 register is 1, A/D conversion is started when a trigger is input
from the ADTRGn pin.
This mode is suitable for applications in which the average of the A/D conversion results is calcu-
lated.
