format
is an optional parameter to specify
the format for the passcode data. Enter B
for binary, D for decimal, and H for
hexadecimal. The default is decimal if
format
is not specified.
size
A decimal number specifying the overall
bit length of the memory bank.
mem bank
Specifies which tag logical memory area
that this command will be applied. If
omitted, it defaults to the EPC memory
area. Other areas include Identification,
User Data, Access area and Kill area.
Enter one of the following values:
‘EPC’ – EPC 12 bytes data area (default)

length
A decimal number specifying the bit
length of a field within a tag. The
maximum length for each DFn field is 64
bits for binary or decimal format. For
hexadecimal format, the bit length can be
up to the maximum bit length specified
for the corresponding memory bank.
