DATA_NOT for Channel C. When Low, data present on DINC[0:7]
is 8B/10B encoded and transmitted serially. When High, special
character sequences are generated as indicated in Table 2.

K-Character Generation for Channel C . KGENC High causes the
data on DINC[0:7] to be encoded into a K-Character. (See Table
2.)
Transmit Data Clock C. When CH_LOCK is Low, this signal is
used to clock data on DINC[0:7], KGENC, and DNC into the
S2009. When CH_LOCK is High, TCLKC is ignored.

DATA_NOT for Channel D. When Low, data present on DIND[0:7]
is 8B/10B encoded and transmitted serially. When High, special
character sequences are generated as indicated in Table 2.
KGEND
TCLKD
K-Character Generation for Channel D. KGEND High causes the
data on DIND[0:7] to be encoded into a K-Character. (See Table
2.)
Transmit Data Clock D. When CH_LOCK is Low, this signal is
used to clock data on DIND[0:7], KGEND, and DND into the
S2009. In Channel Lock Mode, CH_LOCK = High, TCLKD (Low
for at least 16 clocks) is used to reset the Channel Lock state
machine and RX FIFOs.
SYNC

D4
Sync Character. When High, (See Table 2) used to generate a
special sequence of K28.5 charaters. See earlier text.
