TheCurrent register is a write pointer to the ring. The Bound register is aread pointer from the ring. This driver gets the Current register at theinterrupt level and sets the Bound register at the task level. Theinterrupt is never masked at the task level.<p></blockquote><h4>CONFIGURATION</h4><blockquote><p>The W1 jumper should be set in the position of "Software Configuration".The defined I/O address in <b>config.h</b> must match the one stored in EEROM. The RAM address, the RAM size, and the IRQ level are defined in <b>config.h</b>. IRQ levels 2,3,5,7,10,11,15 are supported.<p></blockquote><h4>EXTERNAL INTERFACE</h4><blockquote><p>The only user-callable routines are <b><i><a href="./if_ultra.html#ultraattach">ultraattach</a></i>( )</b> and <b><i><a href="./if_ultra.html#ultraShow">ultraShow</a></i>( )</b>:<dl><dt><b><i><a href="./if_ultra.html#ultraattach">ultraattach</a></i>( )</b><dd>publishes the <b>ultra</b> interface and initializes the driver and device.<p><dt><b><i><a href="./if_ultra.html#ultraShow">ultraShow</a></i>( )</b><dd>displays statistics that are collected in the interrupt handler. </dl><p></blockquote><h4>SEE ALSO</h4><blockquote><p><b><a href="./if_ultra.html#top">if_ultra</a></b><hr><a name="ultraattach"></a><p align=right><a href="rtnIndex.html"><i>Libraries : Routines</i></a></p></blockquote><h1><i>ultraattach</i>( )</h1> <blockquote></a></blockquote><h4>NAME</h4><blockquote> <p><strong><i>ultraattach</i>( )</strong> - publish <b>ultra</b> interface and initialize device</p></blockquote><h4>SYNOPSIS</h4><blockquote><p><pre>STATUS ultraattach ( int unit, /* unit number */ int ioAddr, /* address of ultra's shared memory */ int ivec, /* interrupt vector to connect to */ int ilevel, /* interrupt level */ int memAddr, /* address of ultra's shared memory */ int memSize, /* size of ultra's shared memory */ int config /* 0: RJ45 + AUI(Thick) 1: RJ45 + BNC(Thin) */ )</pre></blockquote><h4>DESCRIPTION</h4><blockquote><p>This routine attaches an <b>ultra</b> Ethernet interface to the network if thedevice exists.
