WHY?&lt;/p&gt;

&lt;p&gt;
for the predefined Registers&lt;br /&gt;
P2^4 = 1;&lt;/p&gt;

&lt;p&gt;
if you have bdata char X;&lt;/p&gt;

&lt;p&gt;
X^2 = 1;&lt;/p&gt;

&lt;p&gt;
It is in the manual. Do not fight the compiler.&lt;/p&gt;

&lt;i&gt;sbit x=0xA4;&lt;/i&gt;&lt;br /&gt;
defines bit 4 of P2&lt;/p&gt;

&lt;p&gt;
&lt;i&gt;please suggest me if there is a method to access the each bit
of register with Base address 0xA4.&lt;/i&gt;&lt;br /&gt;
see a lawyer :) they use and/or&lt;/p&gt;

&lt;p&gt;
it is clear to me that you need some &amp;quot;bible time&amp;quot;&lt;/p&gt;
