    I use ST7FLITE05.

    I want to initialize all the RAM with zero at the beginning of my application.

    How to do? (code in assembler language?)

    Thanks,

    Murielle

    Hi,

    Try this:

    ld X, #64

    lp

    clr ($7f,X)

    dec X

    jrne lp

    this only clears $80 - $bf, it does not cross into the stack area

    hope this helps,

    regards

    Simon
