Sitronix ST7529: need help

Hi,
I am trying to get an LCD display with a built-in Sitronix ST7529
controller going and not having much luck. There are several capacitors
that can be setup to generate the LCD voltage with a multiplier of 2 to 8.
The hardware has been setup for a multiplier of 4. I'm completely unclear
as to how you would determine what multiplier to use. The controller has a
reference voltage generator, a voltage follower, and a booster. I don't
know which of these I need to enable (looks like all for internal
operation with only a single 3.3v supply). There is also an interval
digital pot for setting of the display contrast. I've not been able to
get any voltage out of the power supply section. I do seem to be getting
a status readback from the display. Can anyone help clear this up for me
a bit? The processor being used is a PIC18F4620 BTW.
