11.3.1.1 Using the Transmit command
11.3.1 Transmit command 1Ah
11.3 I-CODE1 and ISO/IEC 15693 label communication commands
The CLRC632 is a fully ISO/IEC 14443 A, ISO/IEC 14443 B, ISO/IEC 15693 and
I-CODE1 compliant reader IC. This enables the command set to be more flexible and
generalized when compared to dedicated MIFARE or I-CODE1 reader ICs.

card communication and related communication protocols.
Table 143. Transmit command 1Ah
The Transmit command reads data from the FIFO buffer and sends it to the transmitter. It
does not return any data. The Transmit command can only be started by the
microprocessor.
To transmit data, one of the following sequences can be used:
When the transmitter requests the next data byte, to ensure that the data stream on the
RF interface is continuous and the FIFO buffer is empty, the Transmit command
automatically terminates. This causes the internal state machine to change its state from
transmit to idle. When the data transmission to the label is finished, the TxIRq flag is set
by the CLRC632 to indicate transmission is complete to the microprocessor.
Remark: If the microprocessor overwrites the transmit code in the Command register
with another command, transmission stops immediately on the next clock cycle. This can
produce output signals that do not comply with the ISO/IEC 15693 standard or the
I-CODE1 protocol.

command is active. Then the command code for the Transmit command is written to
the Command register.
Remark: This is possible for transmission of a data stream up to 64 bytes long.
Since there is not any data available in the FIFO buffer, the command is only enabled
but transmission is not triggered. Data transmission starts when the first data byte is
written to the FIFO buffer. To generate a continuous data stream on the RF interface,
the microprocessor must write the subsequent data bytes into the FIFO buffer in time.
Remark: This allows transmission of any data stream length but it requires data to be
written to the FIFO buffer in time.
command is active. Then the command code for the Transmit command is written to
the Command register. While the Transmit command is active, the microprocessor
can send further data to the FIFO buffer. This is then appended by the transmitter to
the transmitted data stream.
Remark: This allows transmission of any data stream length but it requires data to be
written to the FIFO buffer in time.
