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

44.2.6 A/D Channel Select Register B0 (ADANSB0)

ADANSB0 selects analog input channels for A/D conversion among AN000 to AN007 in group B when group scan

mode is selected. The ADANSB0 register is not used in any scan mode other than group scan mode.

ANSB0n Bit (n = 00 to 07) (A/D Conversion Channel Select)

The ANSB0n bit selects analog input channels for A/D conversion among AN000 to AN007 in group B when group scan

mode is selected. The ADANSB0 register is used for group scan mode only; not used for any other modes. The channels

specified in group A (the channels corresponding to group A, selected with the ADANSA0 and ADANSA1 registers and

the ADCSR.DBLANS[4:0] bits in double trigger mode) should be excluded as the channels to be selected and the

number of channels to be set.

The ANSB000 bit corresponds to AN000 and the ANSB007 bit corresponds to AN007.

When performing A/D conversion of the temperature sensor output or internal reference voltage, do not select analog

input channels. The setting value of this register should be 0000h.

The ANSB0n bit should be set while the ADCSR.ADST bit is 0.
