    There are various ways to toggle a LED via an I/O. The most simple and basic is to toggle an I/O:

    Ex. with LED connected on pin PB0, code in assembler language:

    .loop_toggle

    ld A, PBDR

    xor A, #$01

    ld PBDR, A ; PB0 state changes, PB0 toggles.

    jra loop_toggle ; jump back to loop_toggle label

    Depending on your needs (dedicated frequency, LED to toggle on specific events), another solution is to use a timer and its alternate functions.

    Hope it answers your question.
