READ OPERATION
The read operation is a two-stage operation. First, a word is
shifted in, specifying which register to read. CS is deasserted for
three clock cycles, and then a second word is shifted in to get
the readback data. This second word can be either another
operation or an NOP address. If another operation is shifted in,
it needs to shift in at least eight bits of data to read back the
previous specified data. The NOP address can be used for this
read if there is no need to write/read another register. It is
strongly recommended that the NOP address be used for all
reads for clarity of operations.
Any register read that is less than 16 bits has zeros filled in the
top bits to make it a 16-bit word.
