SPI Read
During a typical read operation, a one-byte address and one-
byte instruction are written to the serial port to instruct the
internal control logic as to which registers are to be accessed.
Register readback data shifts out on the rising edge of SCLK.
The SDO pin is in a high impedance state at all times except
during a read cycle.
