LCD MODULE
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 4 commons. It also
provides control of the LCD pixel data.
The interface to the module consists of 3 control regis-
ters (LCDCON, LCDSE, and LCDPS) used to dene
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
registers are congured to match the LCD panel being
used. Primarily, the initialization information consists of
selecting the number of commons 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 clear/dark pixel respectively.
Once
the
module
is
congured,
the
LCDEN
(LCDCON<7>) bit is used to enable or disable the LCD
module. The LCD panel can also operate during sleep
by clearing the SLPEN (LCDCON<6>) bit.
Figure 13-4 through Figure 13-7 provides waveforms
for Static, 1/2, 1/3, and 1/4 MUX drives.
