Re: [Discuss-gnuradio] Readback Registers

[Matt Ettus]

In the main module, usrp_std.v you can see where we instantiate
serial_io.  There are 4 inputs on that which are the readback registers.
They are distinct from the setting registers.  If you want to readback a
setting register, just store the set value in software instead.
