I am looking at the serial_io.v verilog module. It is my understanding
this module gets an address and data serially through the SDI input and
some FPGA registers according to that input. Is the purpose of having
module to control some parameters directly from software such as
‘interpolation rate’ , ‘ADC offset’ … ?
Also, I am not sure about the origin of master_clock? is that clock on
USRP or is it a signal coming from the FX2 chip?
Thank you ahead of time.
