STAY QUIET (02)
When receiving the Stay Quiet command, the transponder shall enter the Quiet state and shall not send back a response. This
command shall always be executed in Addressed mode (Select flag=0 and Address flag= 1). To exit the Quiet state with a
MLX90129 battery powered, the command “Reset to ready” has to be sent by the reader.

back its value in the response.

WRITE SINGLE BLOCK (21)
When receiving the “Write Single Block” request, the transponder shall write the requested block into internal EEPROM with the
data contained in the request and report the success of the operation in the response. Only the mode with Option_flag set is
supported. That means, the MLX90129 shall wait for the reception of an end of frame (EOF) from the ISO15693 reader and upon
such reception shall return its response.
