Enhanced buffered read read only code (EF):
Response:
The R/W head makes attempts until successful to read a read only code. Only
data that changes is transferred via the interface, i.e. the R/W head transfers data
whenever it reads a new read/write tag or whenever it reads a read/write tag
where there was previously no read/write head within the detection range.
The status '05h' (read command) is output whenever a read/write tag leaves the
detection range.
The length of the read only code that is output depends on the tag type. See table
"Supported Tag Types" on page 33.
