CECCCBI
TUNPVI
UNTSXI
AUTODRI
UPSNEI
CECCRSI
The Corrected ECC Error on Chunk Buffer Memory interrupt status bit reports such an event
to the microprocessor. CECCCBI is set high when an ECC Error that was corrected is
detected during a memory access to the Chunk Buffer Memory. When set, the
CB_DRAMC_COECCE Register will hold the DRAM address that was being accessed when
the ECC Error occurred. CECCCBI and CB_DRAMC_COECCE remain valid when
interrupts are disabled and may be polled to detect error events.
The Corrected ECC Error on Re-sequencing Memory interrupt status bit reports such an
event to the microprocessor. CECCRSI is set high when an ECC Error that was corrected is
detected during a memory access to the Re-sequencing Memory. When set, the
RS_DRAMC_COECCE Register will hold the DRAM address that was being accessed when
the ECC Error occurred. CECCRSI and RS_DRAMC_COECCE remain valid when
interrupts are disabled and may be polled to detect error events.
The transmit unprovisioned error interrupt status bit reports an attempted data transmission to
an unprovisioned Any-PHY channel. TUNPVI is set high upon attempts to transfer data over
the Any-PHY interface to an unprovisioned Any-PHY channel. TUNPVI remains valid when
interrupts are disabled and may be polled to detect an attempt to write data to an
unprovisioned channel.
The Unexpected TSX interrupt status bit reports observation of invalid arrival of TSX to the
microprocessor. UNTSXI is set high when such an event is reported. UNTSXI remains valid
when interrupts are disabled and may be polled.
The Auto Do Not Resequence interrupt status bit reports occurrences of a DO_NOT_ RESEQ
bit in the connection context memory being set automatically as a result of an unacceptably
high number of LOST events being detected on a CI. AUTODRI is set high when such an
event is reported. When set, the Auto Do Not Re-Sequence CI Register (AUTODRICI) holds
the CI number of the last connection to experience an auto do not re-sequence event.
AUTODRI remains valid when interrupts are disabled and may be polled.
The Unexpected Presence of Sequence Number Event interrupt status bit reports unexpected
presence of SN events to the microprocessor. UPSNEI is set high when a sequenced
datagram is received on an Any-PHY channel whose AP_CIOUT configuration bit is set to 0.
UPSNEI remains valid when interrupts are disabled and may be polled.
