Hi, 

 
i use the latest demo version of Keil v9.02a for 8051. When i
simulate a very simple pwm (timer0/1 mode 6) testprogram for a
P89LPC935 the behavior of the simulator seems to be wrong. The
datasheet says on page 53 the following:

Additionally to the inverted display in the logic analyzer i also
noted that the behaviour at one border is incorrect. When loading
THn=0 it shows a constant 0 but when loading THn=0xFF it does not
show a constant 1 but instead still a little 0 peak which should not
occur.&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
