Single Write Words SW
One attempt is made to write <WordNum> 32-bit words from the address <WordAddr>.
Example:
SW1000101ABCD writes the 4-byte-long word "ABCD" from memory address "0001".
Enhanced Write Words EW
This command continuously attempts to write <WordNum> 32-bit words from the address
<WordAddr>. If the command was executed successfully, a status 0 is reported. If there is no
tag in the detection range, or if the tag leaves the detection range, a status 5 is reported.
Example:
EW1000101ABCD continuously writes the 4-byte long word "ABCD" from memory address
"0001".
Command: SW <ChanNo> <WordAddr> <WordNum> <Data> <CHCK> <ETX>
Response: <Status> <ChanNo> <Luii> <UII> <CHCK> <ETX>
F <ChanNo> 0001 <CHCK> <ETX>
Note
The memory bank (MB) parameter defines the bank accessed by this command. see
"Memory Module for Tag Accesses to the "Memory Bank" MB" on page 50.
Note
When writing to the UII/EPC area (MB = 1), note that it is not possible to write to the CRC. The
first writable address is 0x0001. The protocol control word <PC> begins at this address. Use
the command #SW.
Command: EW <ChanNo> <WordAddr> <WordNum> <Data> <CHCK> <ETX>
Response: <Status> <ChanNo> <Luii> <UII><CHCK> <ETX>
Note
The memory bank (MB) parameter defines the bank accessed by this command. see
"Memory Module for Tag Accesses to the "Memory Bank" MB" on page 50.
Note
16-Bit Read/Write Commands
The read/write commands SR, ER, SW, and EW are interpreted as 16-bit versions by means of
a preceding # symbol.
The 16-bit read/write commands behave in the same way as the 32-bit versions.
• 16-bit commands write or read a word with a length of 2 bytes.
• 32-bit commands write or read a word with a length of 4 bytes.
Example:
#SW1000202ABCD corresponds to SW1000101ABCD
