NOTES:
1) T3 mode.
2) E3 mode.
3) HTCLK is a buffered version of either FTCLK or HRCLK and, as such, the duty cycle of HTCLK is
determined by the source clock.
4) In normal mode, HRPOS and HRNEG are sampled on the rising edge of HRCLK and HTPOS and HTNEG are
updated on the rising edge of HTCLK.
5) In inverted mode, HRPOS and HRNEG are sampled on the falling edge of HRCLK and HTPOS and HTNEG
are updated on the falling edge of HTCLK.
