11.3.1.2 RF channel redundancy and framing
11.3.1.3 Transmission of frames of more than 64 bytes
11.3.2 Receive command 16h
Each transmitted ISO/IEC 15693 frame consists of a Start Of Frame (SOF) pattern,
followed by the data stream and is closed by an End Of Frame (EOF) pattern. All I-CODE1
command frames consists of a start pulse followed by the data stream. The I-CODE1
commands have a fixed length and do not need an EOF. The phases of the transmission
sequence are monitored using the PrimaryStatus register’s ModemState[2:0] bits; see
Section 11.2.4 on page
Depending on the ChannelRedundancy register TxCRCEn bit setting, the CRC is
calculated and appended to the data stream. The CRC is calculated using the
ChannelRedundancy register settings.
To generate frames of more than 64 bytes of data, the microprocessor has to write data to
the FIFO buffer while the Transmit command is active. The state machine checks the FIFO
buffer status when it starts transmitting the last bit of the data stream (the check time is
shown in
As long as the internal accept further data signal is logic 1 further data can be written to
the FIFO buffer. The CLRC632 appends this data to the data stream transmitted using the
RF interface.
If the internal accept further data signal is logic 0 the transmission terminates. All data
written to the FIFO buffer after accept further data signal was set to logic 0 is not
transmitted, however, it remains in the FIFO buffer.
Table 144. Receive command 16h
The Receive command activates the receiver circuitry. All data received from the RF
interface is written to the FIFO buffer. The Receive command can be started either by the
microprocessor or automatically during execution of the Transceive command.
