• When
m
= 49, the error correction level is set to the level indicated by the data code word
value.
The rate is set to [n × 10%].
The error correction levels in the following table are determined by the calculation [Data
code word × n × 0.1 = (A)] (round up fractions of 0.5 and over and truncate others).
