Chapter 8 Commands Summary
Write
Multiple
Blocks Writes multiple blocks of user data to an FRAM tag Command = 11
Length = Number of bytes (multiple of 8)
BlockSize = Block size
Data[0-3] = User data (8 bytes) All data bytes are zero
Write AFI Writes 1 byte of information into the Application Family
Identifier (AFI) area contained within block -2 Command = 41
Length = 1
Data[0] = 00xx All data bytes are zero
Lock AFI Locks the 1 byte of information for the AFI area, preventing it
from being modified Command = 42
UIDLow = UIDLow
UIDHi = UIDHi All data bytes are zero
Write DSFID Writes 1 byte of information in the DSFID area Command = 43
Length = 1
Data[0] = 00xx All data bytes are zero
Lock DSFID Locks the 1 byte of information for the DSFID area, preventing
it from being modified Command = 44
UIDLow = UIDLow
UIDHi = UIDHi
Data[0] = 00xx All data bytes are zero
Get System
Information Returns the following system information of the tag:

Clear Multiple
Bytes Clears multiple bytes of user data in a tag Command = 13
Address = Starting byte
Length = Number of bytes to clear
Data[0] = Cleared byte value All data bytes are the cleared byte value
Multi-Tag
Block Read Reads the following information from up to 4 tags in the field:
