The Read command is a 16-bit command. The format
of the command is shown in
The first 6-bits of the Read command determine the
address and the command. The 7th clock will output
the CMDERR bit on the SDO pin. The remaining
9-clocks the device will transmit the 9 data bits (D8:D0)
of the specified address (AD3:AD0).

The read operation requires that the CS pin be in the
active state (V

Byte and Data Byte) is then clocked in on the SCK and
SDI pins. The SDO pin starts driving data on the 7th bit
(CMDERR bit) and the addressed data comes out on
the 8th through 16th clocks.
