RSPE1EN:
The receive small packet error accumulate enable bit (RSPE1EN) enables
counting of minimum packet size violation events. When RSPE1EN is set
high, receipt of a packet that is shorter than 32 bits (CRC-CCITT, Unspecified
CRC or no CRC) or 48 bits (CRC-32) will cause the PMON Configurable
Accumulator #1 register to increment. Small packet errors are ignored when
RSPE1EN is set low.
RFCSE1EN:
The receive frame check sequence error accumulate enable bit (RFCSE1EN)
enables counting of receive FCS error events. When RFCSE1EN is set high,
a mismatch between the received FCS code and the computed CRC residue
will cause the PMON Configurable Accumulator #1 register to increment.
Receive frame check sequence errors are ignored when RFCSE1EN is set
low.
RABRT1EN:
The receive abort accumulate enable bit (RABRT1EN) enables counting of
receive HDLC abort events. When RABRT1EN is set high, receipt of an
abort code (at least 7 contiguous 1's) will cause the PMON Configurable
Accumulator #1 register to increment. Receive aborts are ignored when
RABRT1EN is set low.
RLENE1EN:
The receive packet length error accumulate enable bit (RLENE1EN) enables
counting of receive packet length error events. When RLENE1EN is set high,
receipt of a packet that is longer than the programmable maximum or of a
packet that in not octet aligned will cause the PMON Configurable
Accumulator #1 register to increment. Receive packet length errors are
ignored when RLENE1EN is set low.
RP1EN:
The receive packet enable bit (RP1EN) enables counting of receive error-free
packets. When RP1EN is set high, receipt of an error-free packet will cause
the PMON Configurable Accumulator #1 register to increment. Receive error-
free packets are ignored when RP1EN is set low.
TABRT1EN:
The transmit abort accumulate enable bit (TABRT1EN) enables counting of
transmit HDLC abort events. When TABRT1EN is set high, insertion of an
abort in the outgoing stream will cause the PMON Configurable Accumulator
#1 register to increment. Transmit aborts are ignored when TABRT1EN is set
low.
