I &lt;b&gt;guess&lt;/b&gt; you are asking:&lt;br /&gt;
&amp;quot;can I see the data being written to 0x8000 in P7, the answer is no.  See &amp;quot;the bible&amp;quot; chapter 3.&lt;br /&gt;

Port 7 is SFR 0x96 which can only be accessed via a direct instruction. The XBYTE macro is used to address XDATA memory via a pointer.&lt;br /&gt;
There is no indirect access to the SFR memory area.&lt;br /&gt;
Suggest that you review memory areas idata,data, code and SFR for more info.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: A question about UV3 debug.</title><link>https://community.arm.com/thread/73239?ContentTypeID=1</link><pubDate>Thu, 19 May 2005 22:55:09 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:660c5fcf-0345-4354-878e-e131cbe1073b</guid><dc:creator>Nantian Gumo</dc:creator><description>&lt;p&gt;sorry,I didn&amp;#39;t descript the question clearly.&lt;br /&gt;
When running the command :&lt;br /&gt;
&lt;pre&gt;
P7 = 0X55;
&lt;/pre&gt;
&lt;br /&gt;
The peripherals I/O port7 display well .The question is ,can it display when running the command :&lt;br /&gt;
&lt;pre&gt;
XBYTE[0X8000] = 0X55;//EMIF is configure to P4~P7
&lt;/pre&gt;
&lt;br /&gt;
Thanks all !&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: A question about UV3 debug.</title><link>https://community.arm.com/thread/44055?ContentTypeID=1</link><pubDate>Thu, 19 May 2005 17:15:04 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:f4022b02-d385-46a0-87e6-a28e5c17722a</guid><dc:creator>Al Bradford</dc:creator><description>&lt;p&gt;I&amp;#39;m not sure what device erik is talking about but on my uv3 ver 7.50a and SiLabs driver SiC8051F_uv2 ver 1.6, I can see the PORTs toggle in the peripherals dialog window in simulation mode. I do not have an  -020 target board but I tried the same on an -005 target and I can see the PORTs toggle in the OD configuration.&lt;br /&gt;
One thing very confusing about SiLabs driver is they consider Open Drain as an INPUT and Totem-pole as an OUTPUT. This totally defeats Keil&amp;#39;s Port/Pin definitions in the peripherals dialog. If you attempt to externally toggle a PIN on Totem Pole defined pin, the driver will complain that you have tried to change an output pin.&lt;br /&gt;
Don&amp;#39;t try to get info from SiLbs Tech support. They don&amp;#39;t know an open drain from a flying kite.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: A question about UV3 debug.</title><link>https://community.arm.com/thread/44044?ContentTypeID=1</link><pubDate>Thu, 19 May 2005 11:04:27 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:c5207717-516e-4054-908f-ec86a8d181a1</guid><dc:creator>erik  malund</dc:creator><description>&lt;p&gt;no.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
