11.4.4 Status Tables
The TDMoP status tables hold indications of hardware events. Except where noted, these are latched status bits.
For each bit, the value 1 indicates that the event occurred. A bit set to 1 maintains its value unless the host CPU
changes it. Writing 1 to a bit clears it to 0. Writing 0 to a bit does not change its value. The base address for the
TDMoP status tables is 0x12,000.
11.4.4.1 Per Bundle Status Tables
In the register descriptions in this section, the index n indicates the bundle number: 0 to 63.

Rx_SAToP/CESoPSN_frame_
count_err
SAToP/CESoPSN – packets that belong to structured-
with-CAS bundles were received with incorrect number of
frames.
[3]
Rx_AAL1_cell_hdr_err /
Rx_SAToP/CESoPSN_jump_ove
rflow_err /
R/W
None
AAL1 – AAL1 SAR PDUs received with incorrect SN
(sequence number), protection fields (CRC/parity),
corrected and not corrected AAL1 SAR PDU header.
SAToP/CESoPSN – Packets received with incorrect
sequence number (higher than the expected sequence
number and within the window allowed by the configured
Rx_max_lost_packets value) and could not be inserted
into the jitter buffer due to insufficient space.

None
HDLC – Packet SN (Sequence Number) error outside
window (window of 32768)
SAToP/CESoPSN/AAL1 – Packets discarded due to
incorrect Sequence Number (SN equal to the former or
gap between them exceeds limit determined by
Rx_max_lost_packets parameter).

None
AAL1– Packet sequence number error within window
(determined by Rx_max_lost_packets parameter)
HDLC – Packet sequence number error within window
(window of 32768)
SAToP/CESoPSN – Packets discarded because the Jitter
Buffer reached or was in the over-run state.
[0]
Rx_AAL1_ptr_mismatch /
Rx_SAToP/CESoPSN_miss_
ordered_discard
R/W
None
AAL1 –SAR PDUs received with pointer mismatch
SAToP/CESoPSN – Packets discarded because they
were considered duplicated, or because they were
received too late to be inserted into the Jitter Buffer.
