Operation
(1)
Start timer in the conversion cycle set in DAI12-4(USB)GY.
(2)
At rise edge of internal sampling timer, output A/D conversion
start command to each of DAI12-4 (USB)GY and two
DAI12-4(FIT)GY.
(3)
Because DAI12-4(USB)GY and DAI12-4(FIT)GY together
compose a double buffer, set conversion data in advance before
performing the simultaneous conversion. Because the
converting is performed at the same time, the necessary settling
time is 10
µ
sec for voltage output or 20
µ
sec for current output
per module.
