17.5.5 Contrast Control
17.6 Low-Power Modes
MC68HC908LJ24/LK24 — Rev. 2.1
Freescale Semiconductor
The contrast of the connected LCD panel can be adjusted by configuring
the LCCON[3:0] bits in the LCD control register. The LCCON[3:0] bits
provide a 16-step contrast control, which adjusts the bias voltage in the
resistor ladder for LCD voltage, V

the relative panel potential voltage (V

The V
then adjustments to the bias voltage by the user software to provide
automatic contrast control.
The STOP and WAIT instructions put the MCU in low power-
consumption standby modes.
