OK.  I am no convinced that this answer is NO.  I am now bringing the
secondary JTAG pins out to the debug header, instead of the primary JTAG
pins.  In my system, this seems to imply the following important
considerations:

1. I cannot image an unprogrammed part through my JTAG connector.  I
will have to do this through the serial port.

2. I need to leave DBGSEL unconnected or pull it low at all times.

3. I will have to put something in my code to select the secondary JTAG
pins in the PINSEL1 register EARLY in the boot process.  Once these
instructions have executed, my JTAG debugger will be able to communicate
with the chip.

4. If I push the reset button, I'll lose debug control of the chip until
#3 executes.  I.e., I won't be able to single step through the reset
vector, etc.

Is there anything else I need to think about?

Thanks.
