This data structurecontains <b>M68562_CHAN</b> structures which describe the chip's serial channels.The BSP's <b><i><a href="./sysLib.html#sysHwInit">sysHwInit</a></i>(&nbsp;)</b> routine typically calls <b><i><a href="./sysLib.html#sysSerialHwInit">sysSerialHwInit</a></i>(&nbsp;)</b>which initializes all the values in the <b>M68562_QUSART</b> structure (exceptthe <b>SIO_DRV_FUNCS</b>) before calling <b><i><a href="./m68562Sio.html#m68562HrdInit">m68562HrdInit</a></i>(&nbsp;)</b>.The BSP's <b><i><a href="../bsp/ads360/sysLib.html#sysHwInit2" >sysHwInit2</a></i>(&nbsp;)</b> routine typically calls <b><i><a href="./sysLib.html#sysSerialHwInit2">sysSerialHwInit2</a></i>(&nbsp;)</b> whichconnects the chips interrupts (m68562RxTxErrInt, m68562RxInt, andm68562TxInt) via <b><i><a href="./intArchLib.html#intConnect">intConnect</a></i>(&nbsp;)</b>.<p></blockquote><h4>IOCTL</h4><blockquote><p>This driver responds to the same <b><i><a href="./ioLib.html#ioctl">ioctl</a></i>(&nbsp;)</b> codes as a normal serial driver.See the file <b>sioLib.h</b> for more information.<p></blockquote><h4>INCLUDE FILES</h4><blockquote><p><b>drv/sio/m68562Sio.h</b><p></blockquote><h4>SEE ALSO</h4><blockquote><p><b><a href="./m68562Sio.html#top">m68562Sio</a></b><hr><a name="m68562HrdInit"></a><p align=right><a href="rtnIndex.html"><i>Libraries :  Routines</i></a></p></blockquote><h1><i>m68562HrdInit</i>(&nbsp;)</h1> <blockquote></a></blockquote><h4>NAME</h4><blockquote>  <p><strong><i>m68562HrdInit</i>(&nbsp;)</strong> - initialize the DUSCC</p></blockquote><h4>SYNOPSIS</h4><blockquote><p><pre>void m68562HrdInit    (    M68562_QUSART * pQusart    )</pre></blockquote><h4>DESCRIPTION</h4><blockquote><p>The BSP must have already initialized all the device addresses, etc in<b>M68562_DUSART</b> structure.
