This is the 3-bit short form of the previously described command WRITE_TAG_N. It allows to switch into the
WRITE_TAG mode with a minimum communication time.
The behaviour of the WRITE_TAG command is identical to WRITE_TAG_N with two exceptions:
• WRITE_TAG mode is entered after assertion of the third command bit
• No N parameter is specified with this command; instead the N value which was programmed with the most recent
WRITE_TAG_N command is used. If no WRITE_TAG_N was issued so far, a default N = 0 (transparent mode) will be
assumed.

This command is used to read the antenna phase, which is measured at every carrier cycle.
The response bits D5 to D0 represent the phase (coded binary).

This command specifies the demodulator sampling time ts. The sampling time is coded binary in bits D5 to D0.
