Question on using Ulink 2

Hi,

I have recently started using a Ulink2 unit on an MCB1700 evaluation board with an LPC1768 processor.
It works very well but there is one bit of information I notice i cannot find any description for in any documentation.

The item is the "Sec" value I see in the "Registers" window under "internal".
The value changes when I go from breakpoint to breakpoint but it does not appear to show a real "time passed" value between stopping at breakpoints.
Hence my question; what is this value and how does it work ?

Any help much appreciated.

  • The "time" display is simply a cycle count based on the cycles per instruction for the device that you are simulating and the system clock value that you defined to the simulator. It is not "real" time and it is not based on the PC clock speed.
    You must define the correct target clock frequency and the correct target device to get a "somewhat" simulated operating time between breakpoints.
