SLEEP instruction execution
The LCD module can operate during sleep. The selection is controlled by bit SLPEN
(LCDCON<6>). Setting the SLPEN bit allows the LCD module to go to sleep. Clearing the
SLPEN bit allows the module to continue to operate during sleep.
If a SLEEP instruction is executed and SLPEN = '1', the LCD module will cease all functions and
go into a very low current consumption mode. The module will stop operation immediately and
drive the minimum LCD voltage on both segment and common lines.
operation. To ensure that the LCD completes the frame, the SLEEP instruction should be exe-
cuted immediately after a LCD frame boundary. The LCD interrupt can be used to determine the
frame boundary. See
If a SLEEP instruction is executed and SLPEN = '0', the module will continue to display the current
contents of the LCDD registers. To allow the module to continue operation while in sleep, the
clock source must be either the internal RC oscillator or Timer1 external oscillator. While in sleep,
the LCD data cannot be changed. The LCD module current consumption will not decrease in this
mode, however the overall consumption of the device will be lower due to shutdown of the core
and other peripheral functions.

Note:
The internal RC oscillator or external Timer1 oscillator must be used to operate the
LCD module during sleep.
