E3, DS3 or OC-3 clock select. Setting this bit to zero enables the
C155P/N outputs (pin 30 and pin 31) and enables the C34/C44 output
(pin 53) to provide C8 or C11 clocks. Logic high disables the C155
clock LVDS outputs and enables the C34/C44 output to provide a C34
or C44 clock.
E3 or DS3 clock select. When E3DS3/OC3 bit is set high, a logic low
on the E3/DS3 bit selects a 44.736 MHz clock on the C34/C44 output
and logic high selects a 34.368 MHz clock. When the E3DS3/OC3 bit is
set low, a logic low on the E3/DS3 bit selects an 11.184 MHz clock on
the C34/C44 output and a logic high selects an 8.592 MHz clock.
