Its from Phytec then the input voltage range the same as for the C509&lt;br /&gt;
Controller from Infineon.&lt;br /&gt;
&lt;br /&gt;
Vinmin = Vagnd&lt;br /&gt;
Vinmax = Varef&lt;br /&gt;
&lt;br /&gt;
4V &amp;lt;= Varef &amp;lt;= Vcc + 0.1V and&lt;br /&gt;
Vss - 0.1V &amp;lt;= Vagnd &amp;lt;= Vss + 0.2V&lt;br /&gt;
&lt;br /&gt;
So you can not use it for negative input voltages without any additional extern circuits!&lt;br /&gt;

No? Then, no, there is no register in the 8051 for an external device. At best it&amp;#39;s memory mapped. At worst you have to write a protocol to get the data from it.&lt;br /&gt;
