The Write Multiple Blocks command writes to either one or two blocks of user

data to a FRAM tag. This command will only work on FRAM tags.

Cat.No.56RF-TG-2KB is a FRAM tag.

a. xx:O.Channel[0].Command = 11

b. xx:O.Channel[0].Address = starting block to write

c. xx:O.Channel[0].BlockSize = number of bytes per block

d. xx:O.Channel[0].Data[0…xxx] = data to write

e. xx:O.Channel[0].Length =the number of blocks to write

f. xx:O.Channel[0].Reset = 0

g. xx:O.Channel[0].Timeout = 0

h. xx:O.Channel[0].UIDLow = 0 (or UIDLow)

i. xx:O.Channel[0].UIDHi = 0 (or UIDHi)

If UIDLow and UIDHi are set to 0, this command will operate on the first tag in

the field. Specify a UUID in xx:O.Channel[0].UIDLow and

xx:O.Channel[0].UIDHi to perform the command on a specific tag.

The table below shows the valid values for length, block size and the number of

bytes written or each combination.
