bit0 Reserved bit
• This bit is used to select the conversion mode during the A/D conversion operation.
• Two bit values of MD1 and MD0 allow the selection of either the single conversion mode 1, the
single conversion mode 2, the continuous conversion mode, or the stop conversion mode.
• The meaning of each mode is as follows.
Single conversion mode 1:The continuous A/D conversion from the setting channels of ANS3
Single conversion mode 2:The continuous A/D conversion from the setting channels of ANS3
Continuous conversion mode:The continuous A/D conversion from the setting channels of
Stop conversion mode:The A/D conversion from the setting channels of ANS3 to ANS0 to the
setting channel of ANE3 to ANE0 is repeated and suspended at every
channel until it is forcibly stopped with the BUSY bit. It is not possible
to reactivate while operating. The suspended conversion is restarted by
the start factor occurrence selected by the STS1 and STS0 bits.
Note:
The disabled restart in each of the single, continuous, and stop conversion modes is applied
to the external trigger and software start.
The read value is irregular. Nothing is affected when it is written.
Be sure to set this bit to "0".
