DEBUGGING PROBLEM WITH KEIL UVISION2 V6.01

Luca Zerilli

Hi all,

I'm developing an assembler source code with keil uvision 2 and in the software debug I notice something strange. When I try to put pins P1.0 P1.1 low by external peripherals I/O Port, my code doesn't see variation in the internal register that remains hight (the conditional jump related to doesn't see variation).

It's a software bug or I forget something??

Thank you
Regards

Luca

    Hi, I have the following code

    tc_tm_poll: jnb p1.0,tc_bit_set

    I tried with external I/O Port debug input to put bit p1.0 low and jump to tc_bit_set routine. When I try to put low the bit the code doesn't see variation and doesn't jump to the routine tc_bit_set.

    I haven't initialized the internal register of p1.0 and p1.1. I have developed this code for 80C32 device.

    Thank you for your fast answer
    Regards
