     <dd>Execute the instruction if flag f0 is true. 

<br><dt><code>/fx</code>

     <dd>Execute the instruction if flag f0 is false. 

<br><dt><code>/xt</code>

     <dd>Execute the instruction if flag f1 is true. 

<br><dt><code>/xf</code>

     <dd>Execute the instruction if flag f1 is false. 

<br><dt><code>/tt</code>

     <dd>Execute the instruction if both flags f0 and f1 are true. 

<br><dt><code>/tf</code>
