Example 2 : Sync Word length = 24 bits and Words of 8 bits
Frame description:
Sync = FAF320 Data length = 765 words
Total length = 3 + 765 = 768 words
Frame Sync Configuration:
The Sync length always starts from the
LSB. Right to Left for bit selection.
Hence 24 bits length will only keep FAF320
from the field.
Example 3 : Sync Word length = 30 bits and Words of 10 bits
Frame description:
Sync = FAF33400 Data length = 957 words of 10 bits
Total length = 3 + 957 = 960 words
Frame Sync Configuration:
In this definition, we suppose that the 2 LSB
bits of the Sync Word have to be ignored.
FAF3340 0
Due to our definition of length, we cannot
truncate directly the word, hence, it is
necessary to extend the length to 32bits and to
mask the 2 LSB bits.
