NOTES:
1) T3 mode.
2) E3 mode.
3) In normal mode, LTDAT is sampled on the falling edge of LTCLK/LTCCLK and LRDAT is updated on the
rising edge of LRCLK/LRCCLK.

5)
In inverted mode, LTDAT is sampled on the rising edge of LTCLK/LTCCLK and LRDAT is updated on the
falling edge of LRCLK/LRCCLK.
LRCCLK is enabled. (See Section 4.2 and Figure 1-1, Figure 1-2, and Figure 1-3 for details.)
