[Discuss-gnuradio] understanding writing to registers

[George Nychis]

Okay, so we're trying to get read/write registers to work correctly, and 
we're trying to understand how a register read/write currently works 
using the following methods:
  _write_fpga_reg()
  _write_oe()

We are monitoring the serial I/O enable signal using a logic analyzer 
and writing to registers using the top two methods.  When using them, we 
never see the serial I/O enable signal asserted like we think it should. 
 So we're wondering, what happens when these methods are called?

Second, we are trying to re-write serial i/o to support the read/write 
C/S packets but do not understand serial i/o that well.  We don't quite 
understand the input and output.  Can anyone explain it at all, so we 
understand what we need to change about it and what our new design is 
going to look like?

Thanks!
George
