IUH-F190-V1-*
Operation
If a write command is executed next, all tags in the measurement range that are not "B" tags are
selected. These tags are assigned a 'Selected' flag. The write command is executed only for
tags with no Selected flag.
When the filter is set to "B," command MF12 (Filter Activated - Mode 2) selects all "A" and "C"
tags, and the following commands address the unselected "B" tags.

Difference Between Command MF - Mode 1 and Command MF - Mode 2
In both cases, the subsequent commands are applied only to the "B" tags in the measurement
range.
With MF11, "B" tags are assigned a Selected flag. With MF12, "B" tags are not assigned a
Selected flag.
If a "D" tag with a Selected flag from the operation of a different read/write head enters the
measurement range, this "D" tag will execute the subsequent commands if MF11 is activated. If
MF12 is activated, this "D" tag will not execute the subsequent commands.

tag, and therefore provides information about the chip type of the tag.
