[bits 2, 1, and 0] ANE2, ANE1, and ANE0 (Analog end channel set):
Use these bits to set the A/D conversion end channel.
* When the same channel is written to ANE2 to ANE0 and ANS2 to ANS0, conversion is performed for
one channel only (single conversion).
* In continuous or stop mode, operation returns to the start channel specified in ANS2 to ANS0 after
the conversion is completed for the channel specified in ANE2 to ANE0.
* If the ANS value is smaller than the ANE value, conversion starts from the ANS channel. Then, once
conversion is complete up to channel 7, operation returns to channel 0 and conversion is performed
up to the ANE channel.
* Upon a reset, these bits are initialized to '000.'
Example: ANS=6, ANE=3, single mode
Conversion is performed in the following sequence: CH6, CH7, CH0, CH1, CH2, CH3
