Read Serial Flash Discoverable Parameter (5AH)

The Serial Flash Discoverable Parameter (SFDP) standard provides a consistent method of describing the functional

and feature capabilities of serial flash devices in a standard set of internal parameter tables. These parameter tables can

be interrogated by host system software to enable adjustments needed to accommodate divergent features from multiple

vendors. The concept is similar to the one found in the Introduction of JEDEC Standard, JESD68 on CFI. SFDP is a standard

of JEDEC Standard No.216.
