Writing directly to registers on the FX chip on USRP 1

Hello,

We created a custom board based on the USRP. I’d like to avoid
recompiling the FX (8051) source code if possible. Is there a function
that will allow me to write directly to one of the FX registers? I want
to change the frequency of the CLK output from the default of 12 MHz to
24
MHz.

Thanks,
Eugene.

No command.

FWIW, we run the FX2 at 48 MHz after our f/w is loaded.
