Subject: [lpc2000] Backup RAM
Hi All,

I am using the Phillips LPC2368 micro controller with the GNU
Compiler. The LPC23XX series of controllers have 2kB of battery
backed RAM on chip. I have used the GNU debugger and it appears to me
that the backup RAM is 32bit word addressable. I can confirm that the
main memory is 8bit byte addressable. I have thoroughly read all of
the documentation and it does not mention anything about accessing the
backup memory. Can anybody confirm this?

This being the case does anybody know if I can configure GCC to access
two different memory types?

Has anybody used the backup memory on the LPC23XX series or other
Phillips controllers? Did you have a similar experience and how do
you get around it?

Regards, James Brown
