Sequence Memory (This memory concatenates segments into larger
waveforms):
Size: 32768 entries
Sequence Length: 1 to 32768 entries
Number of Sequences: 1 to 128
Contents of Each Entry:
Designator of which segment to output
Loop Count: # times to repeat the designated
segment (1 to 4096, default = 1)
“Marker Enable” Bit: a mask (default = enabled) for the
marker data in the specified segment
System Use: When square, triangle, or ramp
waveform is selected, one entry is used
