8.4.6.22.1 Our of range 'R'
If the data received exceeds the maximum of 232 bytes, the error R ('Out of range') is
returned.
Note
If performance is important, 232 bytes should be used for plain data and 224 should
be used for enciphered and MACed data, because in this case, the smaller frames
from the DESFire tag are filled up completely.
