BQ40Z50-R1: Activating DISP! pin does not activate LEDs

Part Number: BQ40Z50-R1
Other Parts Discussed in Thread: BQSTUDIOI'm sure there's a simple register setting that I'm missing, but I can't get the LED display to show state of charge when I activate the DISP! pin. I am very clearly transitioning from a high (3.3V) to low (0.12mV) on pin 17 of the fuel gauge, but the LEDs will not display. The LEDs are functional, as I have the gauge set to light LEDs on reset, which they do, but when I activate the DISP! pin (or press the button in BQstudio to activate the LED display) nothing happens. What register am I missing that I need to enable the DISP pin to work?
