2.5.10.3 LCD Drivers
The LCD drivers are grouped into up to six commons (COM0 – COM5) and up to 56 segment drivers.
The LCD interface is flexible and can drive 7-segment digits, 14-segment digits or enunciator symbols.
A voltage doubler and a contrast DAC generate VLCD from either VBAT or V3P3SYS, depending on the
V3P3SYS voltage. The voltage doubler, while capable of driving into a 500 kΩ load, is able to generate a
maximum LCD voltage that is within 1 V of twice the supply voltage. The doubler and DAC operate from
a trimmed low-power reference.
The configuration of the VLCD generation is controlled by the I/O RAM field LCD_VMODE[1:0] (I/O RAM
0x2401[7:6]). It is decoded into LCD_EXT, LDAC_E, and LCD_BSTE.
LCD_VMODE[1:0] configurations.
