■Error details storage area (Un\G41, Un\G4041)
When an error occurs, the bit corresponding to the error details turns on.
When either ID command execution request (Y14, Y1C) is turned off or Result reception (Y16, Y1E) is turned on/off
in Error details storage area (Un\G41, Un\G4041) is cleared.
*1 When Repeat auto, FIFO repeat, Multi-trigger or Multi-repeat is set to Communication specification area (Un\G1, Un\G4001)

Description
Turns on when the specified ID command is incorrect.
Turns on when the number of processing points (read/write) for ASCII/HEX conversion is an odd
number of bytes.
Turns on when data become normal by data correction as a result of read with error correction.
Turns on in the following cases:
• When the number of rewrites is exceeded in the Manage number of writes command.
• When the result of a memory data check (verification) is not normal.
• When the data error occurs as a result of the Read with error correction.
• When the result of an addition operation of the Write calculation overflows.
• When the result of a subtraction operation of the Write calculation underflows.
• When an error occurs as a result of data writing after reading during the Copy command.

Turns on when no communicable RF tags are in the antenna communication area.
Turns on when data are written in an area set as write protected.
Turns on when communication with an RF tag does not end normally.
Turns on when reading or writing is performed exceeding the address range of RF tag.
Turns on when data are not written to the RF tag normally.
Turns on when data are read with ASCII/HEX conversion and the RF tag includes data that cannot be
converted.
Turns on in the following cases:
• The antenna or amplifier is not connected.
• An unavailable antenna is connected.
• The antenna breaks.
