(5) About Trigger conversion clear request
The following describes the trigger conversion clear request.
(a) Trigger conversion clear request
The following figure shows the operation where Trigger conversion completed flag (RX19, RX29) turns off from
on by turning on Trigger conversion completed clear request (RY1A, RY2A) from off.
Even while Trigger conversion completed flag (RX19, RX29) is on, turning on Trigger conversion completed
clear request (RY1A, RY2A) from off allows the A/D converter module to accept a trigger conversion request
and then update the digital operation value.
(b) Method for Trigger conversion completed clear request
The time until Trigger conversion completed flag (RX19, RX29) turns off from on by means of Trigger
conversion completed clear request (RY1A, RY2A) is influenced by the sequence scan time and the link scan
time.
To use Trigger conversion completed flag (RX19, RX29) as an interlock, turn on Trigger conversion request
(RY19, RY29) from off after Trigger conversion completed flag (RX19, RX29) turns off from on.
Remark
Turning on Trigger conversion completed clear request (RY1A, RY2A) from off does not clear CH A/D conversion
completed flag (RX10 to RX13, RX20 to RX23). To clear CH A/D conversion completed flag (RX10 to RX13, RX20 to
RX23), turn on Initial data setting request flag (RY9) from off.
