shorter than 32 bits (CRC-CCITT, Unspecified CRC or no CRC) or 48 bits (CRC-32) will
cause the PMON Configurable Accumulator #2 register to increment. Small packet errors are
ignored when RSPE2EN is set low.
RFCSE2EN:
The receive frame check sequence error accumulate enable bit (RFCSE2EN) enables
counting of receive FCS error events. When RFCSE2EN is set high, a mismatch between the
received FCS code and the computed CRC residue will cause the PMON Configurable
Accumulator #2 register to increment. Receive frame check sequence errors are ignored
when RFCSE2EN is set low.
RABRT2EN:
The receive abort accumulate enable bit (RABRT2EN) enables counting of receive HDLC
abort events. When RABRT2EN is set high, receipt of an abort code (at least 7 contiguous
2's) will cause the PMON Configurable Accumulator #2 register to increment. Receive aborts
are ignored when RABRT2EN is set low.
RLENE2EN:
The receive packet length error accumulate enable bit (RLENE2EN) enables counting of
receive packet length error events. When RLENE2EN 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 #2 register to increment. Receive packet length errors are
ignored when RLENE2EN is set low.
RP2EN:
The receive packet enable bit (RP2EN) enables counting of receive error-free packets. When
RP2EN is set high, receipt of an error-free packet will cause the PMON Configurable
Accumulator #2 register to increment. Receive error-free packets are ignored when RP2EN
is set low.
TABRT2EN:
The transmit abort accumulate enable bit (TABRT2EN) enables counting of transmit HDLC
abort events. When TABRT2EN is set high, insertion of an abort in the outgoing stream will
cause the PMON Configurable Accumulator #2 register to increment. Transmit aborts are
ignored when TABRT2EN is set low.
TP2EN:
The transmit packet enable bit (TP2EN) enables counting of transmit error-free packets.
When TP2EN is set high, transmission of an error-free packet will cause the PMON
Configurable Accumulator #2 register to increment. Transmit error-free packets are ignored
when TP2EN is set low.
