so the whole operator behaves like an inverter.</li>

<li>If the <code class="docutils literal"><span class="pre">cmd</span></code> signal is set to <code class="docutils literal"><span class="pre">one</span></code>, the mask is applied, the

output is the <em>complemented</em> result of the input value <em>ANDed</em>
|

with the mask (suplied by <code class="docutils literal"><span class="pre">constVal</span></code>).</li>
|

|
|
<li>The constant <code class="docutils literal"><span class="pre">constVal</span></code> is given to the macro-generator call,

|
therefore the value cannot be changed afterward : it’s hard wired

in the operator.</li>

register of address zero is stuck to zero. You can write into it,

|

|

<ul class="simple">
|
|||
|
|
<li>datain0 and datain1 are the two write busses. Only one is used to
|
|||
|
|
actually write the register word, it is selected by the sel
|
|||
|
|
signal.</li>
|
|||
|
|
<li>When sel is set to zero datain0 is used to write the register
|
|||
|
|
word, otherwise it will be datain1</li>
|
|||
|
|
<li>adr, adw : the width (Y) of those signals is computed from
|
|||
|
|
regNumber : <code class="docutils literal"><span class="pre">Y</span> <span class="pre">=</span> <span class="pre">log2(regNumber)</span></code></li>
|
|||
|
|
<li>wen and ren : write enable and read enable, allows reading and
|
|||
|
|
writing when sets to <code class="docutils literal"><span class="pre">one</span></code></li>
|
|||
|
|
<li>The DpgenRf1dr0 variant differs from the DpgenRf1d in that the
|
|||
|
|
register of address zero is stuck to zero. You can write into it,
|
|||
|
|
it will not change the value. When read, it will always return
|

zero</li>

this is <code class="docutils literal"><span class="pre">q[3]</span></code>)</li>
