IUH-F190-V1-*, IUT-F190-R4-V1*
Operation
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 52.
Enhanced Read Words ER
Continuous attempts are made to read <WordNum> 32-bit words from the address
<WordAddr>. Only changing data is transferred via the interface. When a read/write tag leaves
the read range, status 5 is output.
Command:
Response:
Example:
ER1000101 continuously reads a 4-byte word from memory address "0001".
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 52.
Single Write Words SW
One attempt is made to write <WordNum> 32-bit words from the address <WordAddr>.
Command:
Response:
Example:
SW1000101ABCD writes the 4-byte-long word "ABCD" from memory address "0001".
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 52.
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.
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.
Command:
Response:
Example:
EW1000101ABCD continuously writes the 4-byte long word "ABCD" from memory address
"0001".
