Manufacturer and Device ID Information
Based on JEDEC publication 106 (JEP106), Manufacturer ID data can be comprised of any number of bytes. Some manufacturers may have
Manufacturer ID codes that are two, three or even four bytes long with the first byte(s) in the sequence being 7FH. A system should detect code
7FH as a “Continuation Code” and continue to read Manufacturer ID bytes. The first non-7FH byte would signify the last byte of Manufacturer ID
data. For Atmel (and some other manufacturers), the Manufacturer ID data is comprised of only one byte.

Deasserting the CS pin will terminate the Manufacturer and Device ID Read operation and put
the SO pin into a high-impedance state. The CS pin can be deasserted at any time and does not
require that a full byte of data be read.
