PRELIMINARY
Digital Local Loopback
The digital local loopback mode interconnects the 16-bit parallel
transmit data and parallel transmit clock input to the 16-bit par-
allel receive data and parallel receive clock output respectively
while maintaining the transmit serial data output. If digital local
loopback is enabled, the receive serial data input is ignored.
"Low" = Digital Local Loopback Mode Enabled
"High" = Disabled
This pin is provided with an internal pull-up.
Loop Timing Mode With No Jitter Attenuation
Hardware Mode When the loop timing mode is activated, the
external local reference clock input to the CMU is replaced with
the 1/16th of the high-speed recovered receive clock coming
from the CDR.
"Low" = Disabled
"High" = Loop timing Activated
This pin is provided with an internal pull-down.
Host Mode This pin is functions as the microprocessor Serial
Data Input.
