Hi:
In the spec. for command packets, there are several different kind of
writes. (register write, SPI write, I2C write). I noticed that
master_control has a few registers, serial_io has a few registers
connected to it. Which one is one? What registers are SPI, I2C or just
registers?

The i2c stuff is all outside the fpga. SPI is a serial bus which is
used to set registers on the daughterboards, in the FPGA, in the AD9862,
etc.
