Hello, 

 
I am debugging with uVision 3 on the C8051F120 uC (on Silabs&amp;#39;
development board) with SiLabs&amp;#39;s debug driver on uVision. Whenever I
try to do single step, the debugger returned the following
message:

The device has SFR banking and D02:0xCB refers to the SFR 0xCB in
Bank 2.&lt;/p&gt;

&lt;i&gt;&amp;quot;*** error 65: access violation at D02:0xCB : no &amp;#39;read&amp;#39;
permission&amp;quot;&lt;/i&gt;&lt;/p&gt;

&lt;p&gt;
What is the address &lt;b&gt;D02:0xCB&lt;/b&gt; supposed to mean?&lt;br /&gt;
Looks a bit odd to me...&lt;/p&gt;

&lt;i&gt;Is there anything I can do?&lt;/i&gt;&lt;/p&gt;

&lt;p&gt;
sure, stop expecting everybody to be concerned with what YOU in
particular am doing. Keil interfaces to many things the f120 being
JUST one of them. Thus expecting Keil to be on top of interfacing to
just that one device is a bit much.&lt;/p&gt;

&lt;p&gt;
Split the stuff and use the tools from those that know what they
are doing. Use the Keil tools to assemble, compile and link and the
SILabs tools &lt;b&gt;separately&lt;/b&gt; to debug.&lt;/p&gt;

&lt;p&gt;
