All output data bytes are shifted out of the device, the most significant bit first. The serial
data output (MISO) is latched on the first falling edge of the serial clock (SCK) after the
command (such as the read from control registers) has been clocked into the device.
Figure 20 shows the reading of a single byte from the device.
