30/55

dac1_mult[5:0]: multiplying factor on dac1_y digital signal before the D/A converters with

0.78% step.

These registers may be used to jump from a reference line (end of that line) to a target line

of the SAME FIELD. However, not all lines can be skipped or repeated with no problems

and, if needed, this functionality should BE USED WITH CAUTION.

lref[8:0] contains, in binary format, the reference line from which a jump is required.

ltarg[8:0] contains the target line as a binary number.

Default values: lref[8:0]:= 000000000 and ltarg[8:0]:= 000000001.
