Table 2-5 ALWG Sequence Data (binary format, big endian)
In the example of Figure 2-34, the total byte length of the pattern data is as follows.
• SPGU 801 number of patterns: x=2 (Pattern1 and Pattern2)
Number of vectors for Pattern1 and Pattern2: N
1
=9, N
2
=9
Total byte length is 20+(6+8×9)+(6+8×9)=176 bytes.
• SPGU 901 number of patterns: x=2 (Pattern1 and Pattern2)
Number of vectors for Pattern1 and Pattern2: N
1
=9, N
2
=7
Total byte length is 20+(6+8×9)+(6+8×7)=160 bytes.
And, the total byte length of the sequence data is as follows.
Number of pattern cycles: x=2 (Pattern1 and Pattern2)
Total byte length is 20+6×2=32 bytes.
