Receive Interrupt Enable Register
This register provides control for enabling or masking
interrupts based on the assertion of status bits in DCLR1,
the Receive Status Register. See Table 7.
Transmit Mode Register
This register contains two control bits associated with
transmission, a general-purpose control bit which drives
a pin on the chip, and a collision counter. See Table 9.

Save short packets if otherwise error free in buffer;
interrupts only for alignment and CRC errors, if
enabled. RX PKT will be set high if short packet
received.

Save packets with short, alignment and/or CRC
errors in buffer; RX PKT will be set high if packet
with error received.
All others
Do Not Use.
Note: Packet acceptance requires both error filter acceptance and address filter acceptance.
