PRBSO
(0)
PRBS
Interrupt.
(PRBSO = 1), an interrupt is
initiated on overflow of PRBS
counter (page 04H, address 10H)
from FFH to 0H. Interrupt vector =
00000010.

Functional Description
7
ODE
(0)
Output Data Enable.
If one, the
DSTo and CSTo output drivers
function normally. When low, DSTo
and CSTo will be tristated.
Note:
When ODE =1, DSTo and
CSTo can be individually tristated
by DSToDE and CSToDE (page
01H, address 16H) respectively.
6
SPND
(0)
Suspend Interrupts.
If one, the
IRQ output (pin 12 in PLCC, 85 in
MQFP) will be in a high-impedance
state and all interrupts will be
ignored. If zero, the IRQ output will
function normally.
5
INTA
(0)
Interrupt Acknowledge.
A zero-to-
one or one-to-zero transition will
clear any pending interrupt and
make IRQ high.
4
TxCCS
(0)
Transmit
Signalling.
If one, the transmit
section of the device is in common
channel signalling (CCS) mode. If
zero, it is in Channel Associated
Signalling (CAS) mode.
Common
Channel
3
RPSIG
(0)
Register
Signalling.
If one, the transmit CAS
signalling will be controlled by
programming page 05H. If zero, the
transmit CAS signalling will be
controlled through the CSTi stream.
