simulate RTCK clock for the ulink2

Hi,

is it possible to simulate the RTCK clock with an simply timer / clock generator?

The problem is, that the RTCK signal from the processor is not available for the jtag connector (using ulink2). This clock is at the beginning of each download or debug session 5kHz. During the init of the processor I start the second crystal - after that the jtag clock could be round about 3MHz.

Are there any things about the RTCK I have to consider? Is the RTCK clock a continouous signal?

thanks in advance
Tim
