<hr/><a name="_details"></a><h2>Detailed Description</h2>
<div class="textblock"><p>We want libnjb to be "endianness agnostic" i.e. the byte-ordering of the libnjb host platform shall not affect its functionality. These routines are written using shifting and byte operations that will produce the same result regardless of whether the host platform is little-endian, big-endian or even mixed-endian.</p>
<p>NJB1 and the "series 3 family" (NJB2, NJB3, NJB Zen, NJB Zen 2.0) have different byte ordering. NJB1 is essentially big-endian, and the series 3 family little-endian. The terminology could be confusing, so we refer to the different endiannesses as "njb1-endian" and "njb3-endian". </p>
