<code>_irq_handler()</code> is called by the GPIO interrupt handler. It will then wake up the <code>at86rf215</code> thread that executes <code>_isr()</code>.</p>
<p>You could also remove the <code>PC_FCSFE_MASK</code> from <code>at86rf215_enable_radio()</code> in <code>at86rf215_internal.h</code> so frames with an invalid checksum are not dropped by the receiver.</p>
