[SOLVED] PIC18F47J53 PORTA Reading Problem??

[xpress_embedo]

Hello!! Everyone!!! I am using PIC18F47J53, and i am not able to read the content of PORTA.

I had connected four Push Buttons on PORTA pin RA0, RA1, RA2 and RA3 (All ar pull high)

But whenever i am trying to read the status of the register i am not able to get it.

Here is my Code:-

#include <p18F27J53.h>
#include<string.h>

// CONFIG1L
#pragma config WDTEN = OFF      // Watchdog Timer (Disabled - Controlled by SWDTEN bit)
#pragma config PLLDIV = 2       // PLL Prescaler Selection (Divide by 2 (8 MHz oscillator input))
#pragma config CFGPLLEN = ON    // PLL Enable Configuration Bit (PLL Enabled)
#pragma config STVREN = OFF     // Stack Overflow/Underflow Reset (Disabled)
#pragma config XINST = OFF      // Extended Instruction Set (Disabled)

// CONFIG1H
#pragma config CPUDIV = OSC1    // CPU System Clock Postscaler (No CPU system clock divide)
#pragma config CP0 = OFF        // Code Protect (Program memory is not code-protected)

// CONFIG2L
#pragma config OSC = HSPLL      // Oscillator (HS+PLL, USB-HS+PLL)
#pragma config SOSCSEL = HIGH   // T1OSC/SOSC Power Selection Bits (High Power T1OSC/SOSC circuit selected)
#pragma config CLKOEC = OFF     // EC Clock Out Enable Bit  (CLKO output disabled on the RA6 pin)
#pragma config FCMEN = OFF      // Fail-Safe Clock Monitor (Disabled)
#pragma config IESO = OFF       // Internal External Oscillator Switch Over Mode (Disabled)

// CONFIG2H
#pragma config WDTPS = 32768    // Watchdog Postscaler (1:32768)

// CONFIG3L
#pragma config DSWDTOSC = INTOSCREF// DSWDT Clock Select (DSWDT uses INTRC)
#pragma config RTCOSC = T1OSCREF// RTCC Clock Select (RTCC uses T1OSC/T1CKI)
#pragma config DSBOREN = OFF    // Deep Sleep BOR (Disabled)
#pragma config DSWDTEN = OFF    // Deep Sleep Watchdog Timer (Disabled)
#pragma config DSWDTPS = G2     // Deep Sleep Watchdog Postscaler (1:2,147,483,648 (25.7 days))

// CONFIG3H
#pragma config IOL1WAY = ON     // IOLOCK One-Way Set Enable bit (The IOLOCK bit (PPSCON<0>) can be set once)
#pragma config ADCSEL = BIT10   // ADC 10 or 12 Bit Select (10 - Bit ADC Enabled)
#pragma config MSSP7B_EN = MSK7 // MSSP address masking (7 Bit address masking mode)

// CONFIG4L
#pragma config WPFP = PAGE_127  // Write/Erase Protect Page Start/End Location (Write Protect Program Flash Page 127)
#pragma config WPCFG = OFF      // Write/Erase Protect Configuration Region  (Configuration Words page not erase/write-protected)

// CONFIG4H
#pragma config WPDIS = OFF      // Write Protect Disable bit (WPFP<6:0>/WPEND region ignored)
#pragma config WPEND = PAGE_WPFP// Write/Erase Protect Region Select bit (valid when WPDIS = 0) (Pages WPFP<6:0> through Configuration Words erase/write protected)
#pragma config LS48MHZ = SYS48X8// Low Speed USB mode with 48 MHz system clock bit (System clock at 48 MHz USB CLKEN divide-by is set to 8)


void main()
{
    unsigned char status;
    ADCON0 = 0xFF;    
    CM1CON = 0xFF;
    
    TRISA = 0xFF;
    PORTA = 0xFF;
    while(1)
    {
        status = PORTA;
    }

}

Whenever i stop my Controller, i am having PORTA=0 in watch window.
Please help me.

dear circuit is more important for debuging.
please upload the circuit diagram also.

The Problem is that, i am not able to upload due to some proxy settings in office.

I had connected 4 Push Button to these ports as shown in this link

ADCON1 not configured.

ADCON0 = 0xFF;
Replacing this line by:-

ANCON0 = 0xFF;

It works, actually i am confused in ADCON and ANCON
