PLL Clock Output Select. With PE=1, when PCS = 1 selects clocks generated from the
PLL for use in outgoing EST1/0 TDM streams, F8o and C8o. Otherwise the clocks are
derived directly from the Input Clock Reference. With C4 as the input clock reference,
EST0/1, 4 and 8 Mb/s timing, as well as F8o and C8o, are generated from the PLL
independent of PCOS. Refer to Table 9, “Clock Modes,” on page 25 and Section 9.2.5
Unused.
C10 Output Enable. When 0, C10o is high impedance. When 1 and the PLL is enabled, C10o
is enabled.
C8 Output Enable. When 0, C8 is high impedance. When 1 and the Input Clock Reference is
not C8, then C8 is enabled.
F8 Output Enable. When 0, F8 is high impedance. When 1 and the Input Clock Reference is
not C8, then F8 is enabled.
C4 Output Enable. When 0, C4 is high impedance. When 1, then C4 is enabled.
F4 Output Enable. When 0, F4 is high impedance. When 1, then F4o is enabled.
C2 Output Enable. When 0, C2 is high impedance. When 1, then C2 is enabled.

D-Channel Receive FIFO Error. Status indicated in “D-Channel BR Status
(DRXS)” on page 68.
D-Channel Receiver attained the message length in MLI mode or the RX FIFO
interrupt trigger level (number of words) in FLI mode.
D-Channel Transmit FIFO empty or 3/4 empty or transmission complete.
Memory empty status for the FSK transmit memory or end of transmission.
Energy Detect Block B interrupt.
Energy Detect Block A interrupt.
