FUNCTION

DISO = 0

OSD signals enabled

DISO = 1

OSD signals disabled

DISV = 0

video signals enabled

DISV = 1

video signals disabled

FPOL = 0

negative feedback polarity; pins 23, 20 and 17 as feedback inputs; no external DAC voltage outputs

FPOL = 1

positive feedback polarity; pins 23, 20 and 17 as external DAC voltage outputs; internal feedback of

signal outputs

BRI = 0

internal brightness control with grey scale tracking

BRI = 1

Brightness control without grey scale tracking. With FPOL = 0 the brightness information is combined

with the internal feedback reference voltages. With FPOL = 1 the brightness information is combined

with the DAC output voltages for DC restoration at the cathodes.
