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

44.2.7 A/D Channel Select Register B1 (ADANSB1)

ADANSB1 selects analog input channels for A/D conversion among AN016 to AN020 and AN027 in group B when

group scan mode is selected. The ADANSB1 register is not used in any scan mode other than group scan mode.

ANSB1n Bit (n = 00 to 04, 11) (A/D Conversion Channel Select)

The ANSB1n bit selects analog input channels for A/D conversion among AN016 to AN020 and AN027 in group B

when group scan mode is selected. The ADANSB1 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 ANSB100 bit corresponds to AN016 and the ANSB111 bit corresponds to AN027.

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 ANSB1n bit should be set while the ADCSR.ADST bit is 0.
