” for details of the attributes.)
These bits set the start and end channel for A/D converter.
Setting of ANE4 to ANE0 the same channel as in ANS4 to ANS0 specifies conversion for that channel
only. (Single conversion)
In continuous or stop mode, conversion is performed up to the channel specified by ANE4 to ANE0.
Conversion then starts again from the start channel specified by ANS4 to ANS0.
If ANS > ANE, conversion starts with the channel specified by ANS, continuous up to channel 31, starts
again from channel 0, and ends with the channel specified by ANE.
Initialized to ANS="00000", ANE="00000" by a reset.
ex. Channel Setting ANS=30ch, ANE=3ch, single conversion mode
Operation : Conversion channel 30ch -> 31ch -> 0ch -> 1ch -> 2ch -> 3ch end
[bit 12 to 8] ANS4-0 (Analog start channel set)
[bit 4 to 0] ANE4-0 (Analog end channel set)
