Device Status on MISO
control bits into the device, the MISO pin reports a 16 bit fixed
device status composed of 2 bytes: Device Fixed Status (bits
15 to 8) + extended Device Status (bits 7 to 0). In a read
operation, MISO will report the Fixed device status (bits 15 to
8) and the next eight bits will be the content of the selected
register.
