The direction of the ramping function is controlled by the
DRCTL pin. A Logic 0 on this pin causes the DRG to ramp
with a negative slope, whereas a Logic 1 causes the DRG to
ramp with a positive slope.
Rev. 0 | Page 28 of 60
The DRG also supports a hold feature controlled via the DRHOLD
pin. When this pin is Logic 1, the DRG is stalled at its last state,
otherwise, the DRG operates normally.
The DDS signal control parameters that are not the destination of
the DRG are taken from the active profile.
