</h3>
<p>
<a name="1207483"> </a><font size=2 face="Verdana, Arial, Helvetica, sans-serif">The first form of the <font size=2 face=Courier><strong>register</strong></font> command associates a symbolic name to an address. This symbolic name can be used with the <font face="Verdana, Arial, Helvetica, sans-serif"><b>r</b></font> option of the <font size=2 face=Courier><strong>display</strong></font> and <font size=2 face=Courier><strong>modify</strong></font> commands. By default the register is word accessed. The size of the register that is whether it is byte or half-word and the type of access can be specified optionally. Several registers can be put into a register group and the <font size=2 face=Courier><strong>display</strong></font> <font face="Verdana, Arial, Helvetica, sans-serif"><b>r</b></font> command lists the values of all of the registers. If the <font size=2 face=Courier><strong>chip</strong></font> command is used to specify the exact core type then it is not necessary to give any <font size=2 face=Courier><strong>register</strong></font> definitions but the list and delete options are still useful inside the debugger.</font>
</p>
<p>
<a name="1207484"> </a><font size=2 face="Verdana, Arial, Helvetica, sans-serif">If the <font face="Verdana, Arial, Helvetica, sans-serif"><b>p</b></font> option is supplied, then a user supplied command procedure is invoked to display the contents of the register when the <font size=2 face=Courier><strong>display</strong></font> command is subsequently used. This is to allow for different register formats, such as big endian. The command procedure is invoked with the following parameter values:</font>

<a name="1207485"> </a><font size=2 face="Verdana, Arial, Helvetica, sans-serif"><font size=2 face=Courier><strong>$1</strong></font> The first parameter of the procedure: it has the value <font size=2 face=Courier><strong>1</strong></font> if the command <font size=2 face=Courier><strong>display</strong></font>⌨️ 快捷键说明
