ETM and IO pins in debug mode

2004-02-09 by Helge Fabricius-Hansen

Hi,

In the manual it says that the ETM pins (P0.22-P0.32) are active 
when DBGSEL and RTCK is high during RESET!

I am reading page 72 and page 206 in the LPC210x manual from Oct. 
02, 2003.

Does this mean that P0.22 - P0.31 not can be used when using a JTAG 
debugger?

My problem is that I get no respons on these pins when my jtag 
debugger is connected. Nor can I change the value of them from 
inside the debugger....!

Anyone with the same problem???
