MLX90132
13.56MHz RFID / NFC Transceiver
6.8 Send command (0x06)
This command is used with the MLX90132 in TAG emulation state, to send data back to the reader. This
command sends specific protocol data without waiting for an answer.

Comments
The anti-collision filter could be activated with the
command “AcFilter”. In this case, the complete
anti-collision process is supported by the
MLX90132 as soon as a “Listen” command is
initiated. The information will be automatically sent
by the MLX90132
The number of slot in which to reply is entered by
the application in the field <Slot number>. In this
case, the MLX90132 automatically manages the
related timings defined by the protocol, to answer
to the corresponding slot. This parameter is used
for the Single Device Detection (SDD) process,
For other commands, the field <Slot number>
should simply be set to zero.
