The following figure shows the operation until Trigger output completed flag (RX19) turns on after Trigger
output request (RY19) is turned on.
• 1) Once Trigger output request (RY19) is turned on, the D/A conversion starts.
• 2) The D/A conversion in CH1 is performed and the analog output value in CH1 is updated. The D/A conversion is
serially performed also for CH2, CH3, and CH4.
• 3) Trigger output completed flag (RX19) turns on when the analog output value is updated in all the channels.
• 4) When Trigger output completed clear request (RY1A) is turned on, Trigger output completed flag (RX19) turns
off.
