According to the datasheet the RDID command (0x9f) returns the following
bytes:
byte 0: Manufacturer ID = 0x01
byte 1,2: Device ID = 0x02, 0x15 (same as S25FL032A)
byte 3: Extended ID = 0x4d
byte 4,5,6: Spansion reserved (do not use).
byte 4 is read as 0x00 on my part, but due to the above explaination, I cannot
say for sure it is always the same, so I had to implement a mask to check for
it.
Best regards,
