Chapter 9 Liquid Crystal Display Driver (S08LCDV1)
Blinking functionality remains active in wait or stop3 mode. If the MCU is in wait or stop3, the LCDRAM
registers cannot be changed. Stop3 provides the lowest power consumption state where the LCD module
is functional.

Depending on the state of the LCDSTP3 bit, the LCD module can operate an LCD panel in stop3 mode.
If LCDSTP3 = 1, LCD module clock generation is turned off and the LCD module enters a power
conservation state.If LCDSTP3 = 0, the LCD module can operate an LCD panel in stop3, and the LCD
module continues to display the current LCD panel contents base on the LCDRAM registers.
If the LCD is enabled in stop3, the ICGERCLK must be selected as the clock source since the bus clock
is not available in stop3.
Depending on the configuration, the LCD module can operate an LCD panel in wait mode. If LCDWAI = 1,
the LCD module clock generation is turned off and the LCD module enters a power conservation state.If
LCDWAI = 0, the LCD module can operate an LCD panel in wait, and the LCD module continues to
display the current LCD panel contents base on the LCDRAM registers.
