	fn = 69
	m = 48, 49

[Description]	• Sets the error correction level for PDF417.

•When m = 48, the error correction level is set by the “Level Setting” and the “Ratio Setting” is canceled. The number of error correction codewords are as follows:

n	Function	Number of error correction codewords
48	Select error correction level 0	2
49	Select error correction level 1	4
50	Select error correction level 2	8
51	Select error correction level 3	16
52	Select error correction level 4	32
53	Select error correction level 5	64
54	Select error correction level 6	128
55	Select error correction level 7	256
56	Select error correction level 8	512

•When m = 49, the error correction level is set by the “Ratio Setting” to the level indicated by the number for encoded data, and the “Level Setting” is canceled. The rate is set to [n ⋅ 10%]. The error correction levels in the following table are determined by the calculation [Data codeword ⋅ n ⋅ 0.1 = (A)] (fractions of 0.5 and over are rounded up, and others are truncated.)

Result (A)	Use the error correction level	Number of error correction codeword
0 to 3	Error correction level 1	4
4 to 10	Error correction level 2	8
11 to 20	Error correction level 3	16
21 to 45	Error correction level 4	32
46 to 100	Error correction level 5	64
101 to 200	Error correction level 6	128
201 to 400	Error correction level 7	256
401 or more	Error correction level 8	512
