RX23W Group 44. 12-Bit A/D Converter (S12ADE)

44.2.8 A/D-Converted Value Addition/Average Function Select Register 0 (ADADS0)

ADADS0 selects the channels 0 to 7 on which A/D conversion is performed successively 2, 3, 4, or 16 times and then

converted values are added (integrated) or averaged.

ADS0n Bit (n = 00 to 07) (A/D-Converted Value Addition/Average Channel Select)

When the ADS0n bit of the number that is the same as that of A/D-converted channel selected by the

ADANSA0.ANSA0n bit (n = 00 to 07) or ADCSR.DBLANS[4:0] bits and ADANSB0.ANSB0n bit (n = 00 to 07) is set

to 1, A/D conversion of analog input of the selected channels is performed successively 2, 3, 4, or 16 times that is set

with the ADC[2:0] bits in ADADC. When the ADADC.AVEE bit is 0, the value obtained by addition (integration) is

stored in the A/D data register. When the ADADC.AVEE bit is 1, the mean value of the results obtained by addition

(integration) is stored in the A/D data register. As for the channel on which the A/D conversion is performed and

addition/average mode is not selected, a normal one-time conversion is executed and the conversion result is stored to the

A/D data register.

The ADS0n bit should be set while the ADCSR.ADST bit is 0.
