    It's weird. I got a 16-bit result. Why? Code :

    Code:
    define OSC 20
DEFINE ADC_BITS 10
DEFINE ADC_CLOCK 3  
DEFINE ADC_SAMPLEUS 10
DEFINE LCD_DREG PORTC
DEFINE LCD_RSREG PORTC
DEFINE LCD_EREG PORTC
DEFINE LCD_EBIT 5 
DEFINE LCD_COMMANDUS 10000'Command delay time in us 
DEFINE LCD_DATAUS 1000 'Data delay time in us
 
ntc VAR WORD

TRISA=%11111111     
ADCON1=%10000010   

PAUSE 4000

lp:

ADCIN 1,ntc
 
PAUSE 100
 
Lcdout $fe,$c0,#ntc

goto lp
    you do not display Tb0 ( as the ADC result ) , but Tb0
    And what are the differences between Tb0 and Tb0? I didn't understand your answer.
