PID FF override value. Used when
selected by pid_ff_override_sel.
This parameter along with
pid_ff_override_sel may be used to
override the HW-computed FF with
a FW computation appropriate for
boost or buck-boost derived
topologies.

Conversion factor for computing
V
OUT
from the measured VSADC
output. This parameter is
computed automatically by the
default FW and requires no action
by the user.
Computed by FW from PMBus
commands as follows:
pid_ff_one_div_vout_scale_loop(U
6.3) = 2^19 /
VOUT_SCALE_LOOP(U0.16), clamp
to 2^9-1
