<p>In a most cases, higher-level routines should be used. These routines are only intended to support development and testing.</p>
<p>Use these routines with great care, and be sure to reference the relevant schematics, data sheets, and source code (i.e., firmware and hdl).</p>
<p>Be careful when mixing these calls with higher-level routines that manipulate the same registers/settings.</p>
<p>These functions are thread-safe. </p>
