I'm using LPC4337with J-link debuger in IAR ide. I noticed that when i connect oscilloscope to the CLK0 pin i'm not able to download the software into CPU and debug, I also see the square signal on CLK0 pin during connection. It seems that CLK0 is internally routed to JTAG pins. Why this is happening? The oscolloscope is 1Mohm 15pF.
