Introduction
The LCD module generates the timing control to drive a static or multiplexed LCD panel, with
support for up to 32 segments multiplexed with up to four commons. It also provides control of
the LCD pixel data.
The interface to the module consists of three control registers (LCDCON, LCDSE, and LCDPS)
used to define the timing requirements of the LCD panel and up to 16 LCD data registers
(LCD00-LCD15) that represent the array of the pixel data. In normal operation, the control regis-
ters are configured to match the LCD panel being used. Primarily, the initialization information
consists of selecting the number of commons and segments required by the LCD panel, and then
specifying the LCD Frame clock rate to be used by the panel.
Once the module is initialized for the LCD panel, the individual bits of the LCD data registers are
cleared/set to represent a turned-on pixel respectively.
Once the module is configured, the LCDEN bit (LCDCON<7>) is used to enable or disable the
LCD module. The LCD panel can also operate during sleep by clearing the SLPEN bit
(LCDCON<6>).
