S3C72M5/C72M7/C72M9/P72M9 (Preliminary Spec)
LCD VOLTAGE DIVIDING RESISTORS
On-chip voltage dividing resistors for the LCD drive power supply one fixed to the V
supplied without an external dividing resistor. Figure 12-4 shows the bias connections for the
S3C72M5/C72M7/C72M9 LCD drive power supply. To cut off the flow of current through the dividing resistor, clear bit
0 of the LCON register.
