Signal Description
Data Input
The input data represents an index to the next sequence table entry to be played by the
AWG module. 2^19 sequence table entries are available.
Data_Select
The data select signal controls which part of the 19 bit internal sequencer index is
loaded from the Data_In pins. If Data_Select is 1 only the Data_In bits 5..0 are used to
load bits 18..13 of the sequencer index. If Data_Select is 0 the Data_In bits 12..0 are
loaded to internal sequencer index 12..0. To load the full 19 sequence index bits first the
upper part needs to be loaded (Data_Select = 1) then the lower part.
Load
A rising edge on the Load signal latches the data present at the Data_In pins into the
respective internal registers. If the Data_Select pin is low the loaded sequencer index is
passed to the sequencer for execution.
