Figure 19.7 shows the flow of ∆Σ A/D conversion initiated by a trigger input.
Figure 19.7 Flow of ∆Σ A/D Conversion Operation (Initiated by a Trigger Input)
Yes
A/D conversion (according
to register settings);
ADF is set to 1 on completion of a round
of conversion for all selected channels
[Operation continues until ADST clearing
condition arises]
Software processing
(setting for the tirgger generating module):
Make settings to negate the trigger input
signal
Software processing:
Set ∆Σ converter registers
Set TRGS0 and TRGS1 to specify tringger
input
Software processing
(setting for the tirgger generating module):
Set conditions for trigger input generation
Software processing:
Clear TRGS0 and TRGS1 to B'00
Continue tirgger-initiated
A/D conversion?
Trigger input generated?
ADST is cleared to 0
ADST is set to 1
