26.2.4
A/D Channel Select Register A0 (ADANSA0)
(1) S12AD.ADANSA0
S12AD.ADANSA0 selects analog input channels for A/D conversion from among AN000 to AN007. In group scan
mode, this register selects group A channels.
ANSA0n Bit (n = 00 to 07) (A/D Conversion Channel Select)
The ANSA0n bit select analog input channels for A/D conversion from among AN000 to AN007. The channels to be
selected and the number of channels can be arbitrarily set. The ANSA000 bit corresponds to AN000 and the ANSA007
bit corresponds to AN007.
When double trigger mode is selected, the channel selected by S12AD.ADCSR.DBLANS[4:0] bits is selected in group
A, and the ANSA0n bit setting is invalid.
The ANSA0n bit should be set while the S12AD.ADCSR.ADST bit is 0.
