Chapter 10 Liquid Crystal Display (LCD32F4BV1) Block Description
LCD32F4BV1 driver system continues to operate during pseudo stop mode. The contents of the LCD
RAM and the LCD registers retain the values they had prior to entering pseudo stop mode.
10.4.4 Operation in Stop Mode
All LCD32F4BV1 driver system clocks are stopped, the LCD32F4BV1 driver system pulls down to VSSX
those frontplane and backplane pins that were enabled before entering stop mode. Also, during stop mode,
the contents of the LCD RAM and the LCD registers retain the values they had prior to entering stop mode.
As a result, after exiting from stop mode, the LCD32F4BV1 driver system clocks will run (if LCDEN =
1) and the frontplane and backplane pins retain the functionality they had prior to entering stop mode.
10.4.5 LCD Waveform Examples
Figure 10-9 through Figure 10-13 show the timing examples of the LCD output waveforms for the
available modes of operation.
