    17 driver</title> <p>In a reference board port, the <filepath>.mmp</filepath> file for the keyboard driver is <filepath>...\template_variant\exkey_inttemplate.mmp</filepath>. This is one of the PRJ_MMPFILES referenced in the template variant's <filepath>bld.inf</filepath> file in the <filepath>...\template_variant\...</filepath> directory, and means that the keyboard driver is built as part of

    18 the Variant. </p> <p>The source for the driver is contained entirely

    19 within <filepath>...\template_variant\specific\keyboard_interrupt.cpp</filepath>. </p> </section>
