(0)
Counter Clear.
If one, all status
counters are cleared and held low.
Zero for normal operation.

Most
Nibble.
If one, the CSTo and CSTi
channel
associated
nibbles will be valid in the most
significant portion of each ST-BUS
time slot. If zero, the CSTo and
CSTi channel associated signalling
nibbles will be valid in the least
significant portion of each ST-BUS
time slot.

64KCCS
(0)
64 Kbits/s Common Channel
Signalling.
If one, common channel
signalling information is sourced
from CSTi, and common channel
signalling information is clocked out
of CSTo. The transmit clock is an
internal clock. This 64 KHz clock is
divided down from C4b and is
synchronous
with
channel boundaries. The rising
edges of the clock occur between
channels 1 and 2; 5 and 6; 9 and
10; 13 and 14; 17 and 18; 21 and
22; 25 and 26; 29 and 30. The
receive clock is synchronous with
the same channel times, but derived
from the extracted clock timebase.
The CCS receive clock is driven out
on Rx64KCK (pin 47 in PLCC, 35 in
MQFP) when this bit is set. If zero
CSTi and CSTo have 2.048 mb/s bit
rates and operate as per Tables 66
to 71.

When unmasked
(AIS16I = 0), a received AIS16 will
initiate an interrupt. Interrupt vector

LOSI
(0)
Loss of Signal Interrupt.
When
unmasked (LOSI = 0) an interrupt is
initiated when a loss of signal
condition exists. Interrupt vector =
01000000.
2
FERI
(0)
Frame Error Interrupt.
When
unmasked (FERI = 0), an interrupt
is initiated when an error in the
frame alignment signal occurs.
Interrupt vector = 00100000.

unmasked (BPVO = 0), an interrupt
is initiated when the bipolar violation
