    hi pardon my ignorance…
    are the following commands reserved or variables or specific commands?
    are they in C?
    i have tried looking the commands in Atmel saoftware frames(ASF) but found none of these.

    if reserved where can i find more info?

    IOPORT_CREATE_PIN()
    pio_configure_pin()
    pmc_enable_periph_clk()
    pwm_init()
    pmc_enable_periph_clk()

    thanks in advance
