Built-in Functions
LCD_DISABLED, LCD_STATIC, LCD_MUX12, LCD_MUX13,
LCD_MUX14
See the devices .h file for other device specific options.
Prescale may be 1-16 for the LCD clock.
Segments0-31 may be any of the following constants or'ed together when
using the PIC16C92X series of chips::
SEG0_4, SEG5_8, SEG9_11, SEG12_15, SEG16_19,
SEG20_26, SEG27_28, SEG29_31 ALL_LCD_PINS
When using the PIC16F/LF1xxx or PIC18F/LFxxxx series of chips, each of the
segments are enabled individually. A value of 1 will enable the segment, 0 will
disable it and use the pin for normal I/O operation.
Segments 32-47 when using a chip with more than 32 segments, this enables
segments 32-47. A value 1 will enable the segment, 0 will disable it. Bit 0
corresponds to segment 32 and bit 15 corresponds to segment 47.

This function is used to initialize the LCD Driver Module on the PIC16C92X and
PIC16F/LF193X series of chips.
Only on devices with built-in LCD Driver Module hardware.
Constants are defined in the devices *.h file.
Examples:
· setup_lcd( LCD_MUX14 | LCD_STOP_ON_SLEEP, 2, ALL_LCD_PINS );
// PIC16C92X
· setup_lcd( LCD_MUX13 | LCD_REF_ENABLED | LCD_B_HIGH_POWER, 0, 0xFF0429);
// PIC16F/LF193X – Enables Segments 0, 3, 5, 10, 16, 17, 18, 19, 20,
21, 22, 23
