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
obtain the readback data. This second word can be either
another operation or an NOP address. If another operation is
shifted in, it must 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 read/write another register. To
maintain the clarity of the operation, it is strongly recommended
that the NOP address be used for all reads.
Any register read that is fewer than 16 bits has zeros filled in the
top bits to make it a 16-bit word.
