Note:
Autoprogram time –> Interface initialization, Erase, Program and Verify (Flash only)
Write time –> Interface initialization, Program (Flash only)
Read time –> Interface initialization, Read (Flash only)
Programming speed – Whole flash programming speed without interface initialization
Read speed – Flash reading speed without interface initialization
