Is there a way to disable markdown and lists?

I would like to get the raw docblock in the XML output. I tried setting
MARKDOWN_SUPPORT = NO, but as far as I can see it doesn't change anything.

The docblock is for example:

/**
 * Helper to update a single bit of an A/B register.
 * - Reads the current register value
 * - Writes the new register value
 */

This becomes this XML output:

<para>Helper to update a single bit of an A/B register.<itemizedlist>
<listitem><para>Reads the current register value</para>
</listitem><listitem><para>Writes the new register value </para>
</listitem></itemizedlist>
</para>

I'm not sure if this is a markdown feature or a separate step, but I would
like to completely disable the parsing of the "- " into "<listitem>", I
would like the docblock as raw as possible. Is there an option for that?
