The sequence data is a program that specifies the order in which the pattern data
is output. The sequence data is used to set up operations such as iteratively
putting out blocks of pattern data for a specified number of times, and jumping
to a specified block when an external event occurs. Sequences allow long
patterns to be set up without preparing large quantities of data.
Sequences can include other sequences (called subsequences) so that you can
make complex sequence program easier. Sequence data is transferred to the
pattern generation unit sequence memory, and controls the operation of the
pattern control circuit. Using the run mode, which is described in detail later, you
can select whether all the sequence data is valid or whether enhanced mode
settings such as event jumps in the sequence are ignored.
Operating Modes Overview
In the run modes, pattern output is controlled by the pattern generation unit’s
pattern control circuit. The DG2030 supports four run modes: repeat, single,
step, and enhanced. These run modes are specified with the SETUP

Run
Mode menu. Table 2-3 provides functional information for each mode.

Run mode
Function
Repeat
Repeats the pattern data from the first to last data point indefinitely.
If a sequence isdefined, iteratesthe output according to that
sequence.
Single
Outputs the pattern data once from the first to last data point in point
order. If a sequence isdefined, outputsthe pattern once according to
that sequence.
Step
Operatesidentically to repeat mode, except that just one data point
isoutput each time the
STEP/EVENT
button is pressed.
Enhanced
Same asRepeat with the addition that event jumpsand trigger waits
are also effective.
NOTE
. The Repeat, Single, and Step modes ignore the event jump and trigger
wait settings.
