Re: ETM disabled with primary JTAG enabled on LPC2109.

2004-10-05 by lpc2100_fan

Hi,

I guess you are talking about the LPC2106 (there is a LPC2119) so I
don't really know which one you are referring to. The LPC2106 offers
the option to enable all debug channels, primary JTAG AND ETM or the
secondary JTAG (Application Note see in the "Files" section of this
user group)
The LPC2119 (or LPC2114) offer less RAM but more I/O and the option to
enable JTAG OR ETM or both.

Cheers, Bob
