(New) When Aden Is 0, No Trigger Will Be Accepted - Epson S1C17624 Technical Manual

24 a/D COnVeRTeR (aDC10)
D1 aDCTl: a/D Conversion Control Bit
Controls A/D conversion.
1 (W): Software trigger
0 (W): Stop A/D conversion
1 (R): Being converted
0 (R): Conversion completed/standby (default)
Write 1 to ADCTL to start A/D conversion by a software trigger. If any other trigger is used, ADCTL is
automatically set to 1 by the hardware.
ADCTL remains set while A/D conversion is underway. In one-time conversion mode, upon completion
of A/D conversion in the specified channels, ADCTL is reset to 0 and the A/D conversion circuit stops
operating. To stop A/D conversion during operation in continuous conversion mode, reset ADCTL by
writing 0.
When ADEN is 0, no trigger will be accepted.
D0 aDen: aDC10 enable Bit
Enables or disables the A/D converter operations.
1 (R/W): Enabled
0 (R/W): Disabled (default)
Writing 1 to ADEN enables the A/D converter, meaning it is ready to start A/D conversion (i.e., ready
to accept a trigger).
When ADEN is 0, the A/D converter is disabled, meaning it is unable to accept a trigger. However, set-
ting ADEN to 0 does not stop A/D conversion being currently executed. To stop A/D conversion, write
0 to ADCTL.
Before setting the modes, start/end channels, or other A/D converter conditions, be sure to reset ADEN
to 0. This helps to prevent the A/D converter from operating erratically.
