Receive Signaling Change of State FIFO Depth Threshold
Overflow Status. This status bit reflects the actual depth of the
FIFO entries as compared to the threshold programmed by the
host. When set to 1, the threshold is currently exceeded. When
set to 0, the number of FIFO entries is less than the programmed
threshold.
Receive Signaling Change of State FIFO Timer Threshold.
This number can be programmed from 0 to 0xFFFF. The value
indicates the number of 125 µs increments that the timer
counts before interrupting the processor. The associated inter-
rupt status bit will be set only if there are valid entries in the
FIFO. When set to 0, the timer is disabled and no interrupt will
be generated. The maximum timer setting is 8 s.
Receive Signaling Change of State FIFO Status. These
bits are located at the address for the signaling change of
state FIFO. These status bits have the following definitions:
01 = The entry being read is the last valid entry.
11 = The entry being read is not the last valid entry.
00 = The entry being read is not valid and should be ignored.
COS Link Number. These bits are located at the address for
the signaling change of state FIFO. This number indicates
the particular link from which a signaling change of state has
been detected.
COS Time-Slot Number. These bits are located at the
address for the signaling change of state FIFO. This number
indicates the particular time slot in which a signaling change
of state has been detected.
New Signaling Code. These bits are located at the address
for the signaling change of state FIFO. This value indicates
the new signaling state received.
