NOTES:
1) T3 mode.
2) E3 mode.
3) FRCLK is a buffered version of either FTCLK or HRCLK and, as such, the duty cycle of FRCLK is
determined by the source clock.
4) FTSOF is configured to be an input.
5) FTSOF is configured to be an output.
6) In normal mode, FTD (and FTSOF if it is configured as an input) is sampled on the rising edge of FTCLK and
FRDEN, FRD, FRSOF, and FTDEN (and FTSOF if it is configured as an output) are updated on the rising
edge of FRCLK or FTCLK.
7) In inverted mode, FTD (and FTSOF if it is configured as an input) is sampled on the falling edge of FTCLK
and FRDEN, FRD, FRSOF, and FTDEN (and FTSOF if it is configured as an output) are updated on the
falling edge of FRCLK or FTCLK.
