6.7 Read Command
    The Read command is used to read data from either the
            Configuration zone or the EEPROM Data zone. The Configuration zone is always readable
            and can be read 16 bytes at a time. Data zone slots that allow reading can be read 32
            bytes at a time. Multiple reads are required to completely read some data slots. Data
            slots 0 and 3 can never be read and an execution error will occur if so attempted.  Data
            slots 1 and 2 can always be read in the clear.
