4-buffer mode operation (timer trigger select: 4 buffers)
In this mode, A/D conversion of one analog input is executed four times, and the results are stored
in the ADCRnm register.
One analog input is A/D converted four times using the timer event signals (TR0ADTRG0,
TR0ADTRG1, TR1ADTRG0, TR1ADTRG1, INTTR0CD, INTR0OD, INTTR1CD, INTTR1OD) as a
trigger, and the results are stored in four ADCRnm registers. The A/D conversion end interrupt
(INTADn) is
generated when the four A/D conversions end.
After conversion has finished, the next conversion is repeated when a timer event signal is
generated, unless the ADCEn bit of the ADMn0 register is cleared to 0.
This mode is suitable for applications in which the average of the A/D conversion results is
calculated.
