I am going through the UTMI specs Version 1.05. On page 22 of UTMI specs, it was told that
"
1. FS ONLY implementation of the UTM would provide 32 CLK cycles per byte time.
2. LS ONLY implementation of the UTM would provide 32 CLK cycles per byte time. "

But in the page 25, it was written that
"
The clocking of the HS/FS UTM in the FS Mode is similar to FS Only and LS only implementations,
except that for FS Only and LS Only implementations there are only 8 CLK cycles per byte time.
".
I am confused with the statements above. It is not clear whether FS Only or LS only will take 32 CLK cycles per byte time or 8 CLK cycles per byte time.
