How to connect with JTAG

 How to connect with JTAG

Hi,
I am new to ARM architecture and Keil tools.

I am using LM3S9B91 eval board from Luminary and Keil MDK with ULink2. When I start the program, JTAG will reset the processor and program counter will also be reset.
Is there any way to connect to a processor which is already running code without resetting the processor.
For example if the processor is already running the instructions and when the JTAG is connected, it will pause the processor and all the memory contents can be verified?
An extension to the above question:
If it is possible to connect the processor without resetting, is it possible to continue in the debugger (for example step by step debug etc).

Your help is really appreciated.

Thanks,
John
