I am working on a project wherein LPC2468 is being used with CCLK
= 72MHz. With this frequency, I used following two options: 
&amp;gt;&amp;gt; PCLKSEL1.PCLK_TIMER3 = 0x2 
Here the Clock of timer3 runs @ CCLK/2 = 36MHz with a resolution of
27.78ns

Do you support nested interrupts?&lt;/p&gt;

&lt;p&gt;
Have you checked the function of this timer interrupt (for example
driving a GPIO pin) when you _only_ have timer 3 enabled to generate
interrupts?&lt;/p&gt;

&lt;p&gt;
Next thing - are your only validation of the timer interrupt the
repeat frequency of CAN frames? What speed are you running the CAN
interface at? 10k frames/second is a very high bus load. And what
size are each CAN frame?&lt;/p&gt;

&lt;p&gt;
I think your problem isn&amp;#39;t timer3 but the max speed you manage to
get the CAN controller to send out frames.&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
