ADnTRGCH26 to ADnTRGCH24 bits

ADnTRGCH26 to ADnTRGCH24 bits
ADnTRGCH22 to ADnTRGCH20 bits
Setting the ADnCH2 register is enabled when a conversion operation is enabled (ADnSCM.ADnCE bit = 1) in
the extension buffer mode. When the first selection trigger 2 is generated after the conversion operation is
enabled (ADnCE bit = 1), the analog input pin specified by the ADnTRGCH22 to ADnTRGCH20 bits is
selected and A/D conversion is executed. When the next selection trigger 2 is later generated, the analog
input pin specified by the ADnTRGCH26 to ADnTRGCH24 bits is selected and A/D conversion is executed.
After that, the analog input pins are alternately selected for output each time selection trigger 2 is generated.
If an error occurs (when selection trigger 2 is generated during A/D conversion), the analog input pin specified
by the ADnTRGCH22 to ADnTRGCH20 bits and the analog input pin specified by the ADnTRGCH26 to
ADnTRGCH24 bits are alternately selected, but the selected analog input pin is not changed because A/D
conversion is in progress.
