Datasheet Rev L,

In table 8 the size of CFI data and the byte address range are not consistent. Range 00020h~000CEh (Here is also a typo in the table) means the size = 206d - 32d + 1d = 175 but the table scribed 174 which is confusing.

Also, is the ID/CFI ASO support Continuous & Linear Synchronous Read? The datasheet mentions SSR support both async/sync read but doesn't tell if ID/CFI supports it or not. 

Thank you.

Regards,

Keter

Hello,

Thanks for pointing out the ID/CFI address mismatch. We confirmed that Table 8 CFI data structure address should be 20h to BEh as shown in Table 44. The data size is 159. We will correct the datasheet.

 

Burst read is also supported in ID/CFI region.

Thank you

Regards,

Bushra
