Device Geometry Definition
“n” such that device size = 2
Flash device interface code assignment:
"n" such that n+1 specifies the bit field that represents the flash device w idth
capabilities as described in the table:
“n” such that maximum number of bytes in w rite buffer = 2
Number of erase block regions (x) w ithin device:
Erase Block Region 1 Information
Erase Block Region 2 Information
Reserved for future erase block region information
1. x = 0 means no erase blocking; the device erases in bulk
2. x specifies the number of device regions w ith one or

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
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
