    Default Problem with 16F877A but not with 16F876A

    I have use the 16f876a for a frequency meter (base on AN592), and works fine.
    Yesterday i test the same programm with 16f877a but not work and i don't why.

    My configuration is:
    ' PIC16F877A
    ' Xtal 4MHZ

    CMCON = 7 ' PortA = digital I/O
    ADCON0 = %11100001
    ADCON1 = %10000000
    TRISA = %11111111

    The same configuration work with 16F876A.
