PIC16F193X/LF193X
26.2
The LCD module has 3 possible clock sources:
• F
• T1OSC
• LFINTOSC
The first clock source is the system clock divided by
256 (F
about 1 kHz output when the system clock is 8 MHz.
The divider is not programmable. Instead, the LCD
prescaler bits LP<3:0> of the LCDPS register are used
to set the LCD frame clock rate.
The second clock source is the T1OSC. This also gives
about 1 kHz when a 32.768 kHz crystal is used with the
Timer1 oscillator. To use the Timer1 oscillator as a
clock source, the T1OSCEN bit of the T1CON register
should be set.
The third clock source is the 31 kHz LFINTOSC, 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.

A 4-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 LP<3:0> bits of the LCDPS register,
which determine the prescaler assignment and prescale
ratio.
The prescale values are selectable from 1:1 through
1:16.
