“n” such that maximum number of bytes in write buffer = 2n
2Ch
Number of erase block regions within device:
1. x = 0 means no erase blocking; the device erases in “bulk”
1
2. x specifies the number of device or partition regions with one or more
contiguous same-size erase blocks
3. Symmetrically blocked partitions have one blocking region
4. Partition size = (total blocks) x (individual block size)
Notes:
1.
The value is 32 Bytes buffer write typical time out
