Bit Set
Reads the specified number of bytes from the specified start address and sets the specified bits to 1.
For the Designation Data, set a hexadecimal value with the bits to be set to 1 turned ON.
Up to 4 bytes (i.e., 2 words) can be specified for one command execution.
The following example shows specifying 0120 hex for 2 bytes of data to set bit 0 in byte 1 and bit 5 in
byte 2.
• Data status will not be changed for any bit that is OFF in the Designation Data.
• Verification will not be performed if No Verification is set for writing.
• Check the memory capacity of the RF Tag before setting the Processing Address and Number of Processing Bytes. If
the Processing Address and Number of Processing Bytes are not suitable for the RF Tag for which communications
are being performed, the RF Tag Address Error Flag (CIO n+8, bit 13) will turn ON.
