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
maximum 3.3V to approximate 2.45V.
The STOP and WAIT instructions put the MCU in low power-
consumption standby modes.
The LCD driver module continues normal operation in wait mode. If the
LCD is not required in wait mode, power down the LCD module by
clearing the LCDE bit before executing the WAIT instruction.
For continuous LCD module operation in stop mode, the oscillator stop
mode enable bit (STOP_XCLKEN in CONFIG2 register) must be set
before executing the STOP instruction. When STOP_XCLKEN is set,
CGMXCLK continues to drive the LCD module.
If STOP_XCLKEN bit is cleared, the LCD module is inactive after the
execution of a STOP instruction. The STOP instruction does not affect
LCD register states. LCD module operation resumes after an external
interrupt. To further reduce power consumption, the LCD module should
be powered-down by clearing the LCDE bit before executing the STOP
instruction.
