Some CONFIG directives are intended to be used once. Others can be used multiple times. For example you can specify that a port must be set to input after you have specified that it is used as an input.
You cannot change the LCD pins during run time. In that case the last specification will be used or an error message will be displayed.
CONFIG 1WIRE
Action
Configure the pin to use for 1WIRE statements and override the compiler setting.
Syntax
CONFIG 1WIRE = pin
Remarks
Pin 
The port pin to use such as PORTB.0
The CONFIG 1WIRE statement, only overrides the compiler setting.
You can configure only one pin for the 1WIRE statements because the idea is that you can attach multiple 1WIRE devices to the 1WIRE bus.
You can however use multiple pins and thus multiple busses. All 1wire commands and functions need the port and pin in that case.
The 1wire commands and function will automatically set the DDR and PORT register bits to the proper state. You do not need to bring the pins into the right state yourself.
It is important that you use a pull up resistor of 4K7 ohm on the 1wire pin. The build in pull up resistor of the AVR is not sufficient.
Also notice that some 1wire chips also need +5V.

CONFIG ADC
Action
Configures the A/D converter.
Syntax
CONFIG ADC = single, PRESCALER = AUTO, REFERENCE = opt
Remarks
ADC |
Running mode. May be SINGLE or FREE. |
PRESCALER A numeric constant for the clock divider. Use AUTO to let the compiler generate the best value depending on the XTAL
REFERENCE Some chips like the M163 have additional reference options.
Value may be OFF , AVCC or INTERNAL. See the data sheets for the different modes.
Some newer micro's support also : INTERNAL_1.1
INTERNAL_2.56
INTERNALEXTCAP

ASM
The following ASM is generated(depending on the chip)
In _temp1,ADCSR ; get settings of ADC
Ori _temp1, XXX ; or with settings
