Description

27h

“n” such that device size = 2n in number of bytes

Flash device interface code assignment:

"n" such that n+1 specifies the bit field that represents the flash device width

capabilities as described in the table:

28h

x64

x32

x16

2Ah

“n” such that maximum number of bytes in write buffer = 2n

Number of erase block regions (x) within device:

1. x = 0 means no erase blocking; the device erases in bulk

2Ch

2. x specifies the number of device regions with one or more contiguous

same-size erase blocks.

3. Symmetrically blocked partitions have one blocking region

Erase Block Region 1 Information

bits 0-15 = y, y+1 = number of identical-size erase blocks

bits 16-31 = z, region erase block(s) size are z x 256 bytes

Erase Block Region 2 Information

31h

bits 0-15 = y, y+1 = number of identical-size erase blocks

bits 16-31 = z, region erase block(s) size are z x 256 bytes

35h

Reserved for future erase block region information
