DESCRIPTION
“n” such that device size = 2
Flash device interface: x8 async, x16 async, x8/x16 async;
28:00 29:00, 28:01 29:00, 28:02 29:00
buffer = 2
Number of erase block regions within device:
1. x = 0 means no erase blocking; the device erases in “bulk”
2. x specifies the number of device or partition regions
3. Symmetrically blocked partitions have one blocking
4. Partition size = (total blocks) x (individual block size)
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
“n” such that maximum number of bytes in write
Erase Block Region 1 Information
with one or more contiguous same-size erase blocks
