Runs the Reset- and Initialisation
Phase.
3Fhex _{Note: This command can not be}
-
activated by software, but only by a
Power-On or Hard Reset
00hex
No action: cancels current command
execution.
-
1Ah e x
Transmits data from the FIFO buffer to
the label.
Data Stream
Activates Receiver Circuitry.
Note: Before the receiver actually
starts, the state machine waits until the
time configured in the register RcvWait
16hex has passed.
-
Note: This command may be used for
test purposes only, since there is no
timing relation to the Transmit-
Command .
Transmits data from FIFO buffer to the
label and activates automatically the
receiver after transmission.
1Ehex
Note: Before the receiver actually
starts, the SL RC400 waits until the Data Stream
time configured in the register RcvWait
has passed.
Note: This command is the
combination of Transmit and Receive
01hex
Gets data from FIFO buffer and writes
it to the internal E²PROM.
Start Address LSB
Start Address MSB
Data Byte Stream
03hex
Reads data from the internal E²PROM
and puts it into the FIFO buffer.
Start Address LSB
Start Address MSB
Number of Data Bytes
07hex
Reads data from E²PROM and
initialises the SL RC400 registers.
Start Address LSB
Start Address MSB
12hex
Activates the CRC-Coprocessor.
Note: The result of the CRC
calculation can be read from the
registers CRCResultLSB and
CRCResultMSB
