Secondary JTAG port

Started by bettymitmachtv December 23, 2003
has anyone used the secondary JTAG port so far? I need as many as
possible IO lines for my application and consider to use the
secondary JTAG port for debugging.

As I understand some software inside the FLASH has to enable the
secondary JTAG. Any "app note" for doing this?

I have some documentation, I will post it when I am back to my
computer. --- In , "bettymitmachtv" <postkasten@s...>

I have uploaded an application note on using the secondary JTAG to
the files section. Richard
