Procedure for RING format
When using ring format, a ring memory area large enough for the data to be set is reserved.
Data cannot be modified during DA conversion.
Clock
The sampling clock controls the sampling frequency. You can select either the internal sampling clock, or
external sampling clock. The sampling clock is selected by means of software.
-
Internal sampling clock
The clock signal from the on-board clock generator is used.
-
External sampling clock
The edge of the digital signal input from an external device is used for the sampling clock.
Start Condition
The condition for controlling the start of sampling can be selected from among software, external trigger.
The conditions for controlling the start and stop of sampling are completely independent of each other;
they can be set separately.
-
Software
The board starts sampling and storing input data to memory immediately after the operation start
command is issued.
-
External trigger
The board starts waiting for an external control signal as soon as the operation start command is
output.
Sampling and data transfer from memory start when the specified edge (rising edge or falling edge)
is input from the external control signal.
