register S2
) is
required before issuing this command, otherwise if

to return in command mode.

Note: After issuing this command, if the device is in conversation, to send other
commands to the device you must return to command mode by issuing the escape
sequence (see
register
S2
) or tying low
DTR
pin if
&D1
option is active.
