packet will cause the PMON Configurable Accumulator #1 register to
increment. Transmit error-free packets are ignored when TP1EN is set low.
RSPE2EN:
The receive small packet error accumulate enable bit (RSPE2EN) enables
counting of minimum packet size violation events. When RSPE2EN 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 #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. (Receipt of a packet that is both too
long and not octet aligned results in only one 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.
