22.2
The LCD driver module has 3 possible clock sources:
• (F
• T13CKI-Clock/32
• INTRC/32
The first clock source is the system clock divided by
8192 ((F
provide about 1 kHz output when the system clock is
8 MHz. The divider is not programmable. Instead, the
LCD prescaler bits, LCDPS<3:0>, are used to set the
LCD frame clock rate.
The second clock source is the Timer1 oscillator/32.
This also gives about 1 kHz when a 32.768 kHz crystal
is used with the Timer1 oscillator. To use the Timer1
oscillator
(T1CON<3>) bit should be set.

The third clock source is a 31.25 kHz internal RC
oscillator/32, which provides approximately 1 kHz
output.
The second and third clock sources may be used to
continue running the LCD while the processor is in
Sleep.
Using the bits, CS1:CS0 (LCDCON<3:2>), any of these
clock sources can be selected.
22.2.1
A 16-bit counter is available as a prescaler for the LCD
clock. The prescaler is not directly readable or writable;
its value is set by the LP3:LP0 bits (LCDPS<3:0>), which
determine the prescaler assignment and prescale ratio.
The prescale values from 1:1 through 1:32768 in
power-of-2 increments are selectable.
