Description<br />
4:2 TPL 3 Transmit Preamble Length<br />
Determines the number of preamble<br />
bytes the transmitter sends be<strong>for</strong>e it<br />
starts to transmit data. The send pattern<br />
is defined by the TPPT bits.<br />
000 - No Preamble (Default)<br />
001 - 1 byte<br />
010 - 2 bytes<br />
011 - 4 bytes<br />
100 - 6 bytes<br />
101 - 8 bytes<br />
110 - 16 bytes<br />
111 - Reserved<br />
1 TINV 1 1 TINV 1 Transmit bit stream inversion<br />
0 - No invert.<br />
1 - Invert the data be<strong>for</strong>e it is sent to the<br />
DPLL.<br />
Setting TINV to ‘1’ generates FM1 from<br />
FM0, NRZI mark from NRZI space, etc.<br />
It also inverts the bit stream in NRZ<br />
mode.<br />
0 TCL 1 Transmit Clock Invert<br />
0 - Normal operation - Data is shifted<br />
out on the falling edge. (Default.)<br />
1 -The internal transmit clock is<br />
inverted by the MPSC be<strong>for</strong>e it is used.<br />
This allows the MPSC to clock data out<br />
half a cycle earlier on the rising edge of<br />
the clock.<br />
