(3) A-D conversion start bit (bit 6)
(4) A-D conversion frequency (
This bit is used to select the source of trigger occurrence. (Refer to “(3) A-D conversion start bit.”)
As shown in Table 8.2.1, the operating time of the A-D converter varies depending on the selected
operating clock (
Since the A-D converter’s comparator consists of capacity coupling amplifiers, keep that
kHz during A-D conversion.
A-D conversion frequency (
Setting this bit to “1” generates a trigger, causing the A-D converter to start operating. Clearing
this bit to “0” causes the A-D converter to stop operating.
In the one-shot mode or single sweep mode, this bit is cleared to “0” after the operation is
completed. In the repeat mode or repeat sweep mode, the A-D converter continues operating until
this bit is cleared to “0” by software.

A-D converter to start operating. The A-D converter stops when this bit is cleared to “0.”
In the one-shot mode or single sweep mode, this bit remains set to “1” even after the operation
is completed. In the repeat mode or repeat sweep mode, the A-D converter continues operating
until this bit is cleared to “0” by software.
