7.4.3.10.1 Read failure 'F'
This error is returned if the reader receives either bad data or the block address
exceeds the block address range of the sector.
7.4.3.10.2 No tag in field 'N'
The tag does not respond. There is either no tag present or not addressed.
7.4.3.10.3 Operation mode failure 'O'
The block address of the 'r' command is higher than 40h.
The block address of the 'r' command conflicts with other commands, therefore the
block address has to be limited to 40h.
Use the 'rb' command instead.
