RWR Receive Watchdog Release. The time (in bit-times) from
sensing dropped carrier to releasing watchdog timer.
0: 24 bit-times
1: 48 bit-times

RWD Receive Watchdog Disable
0: If the received packet‘s length exceeds 2560 bytes, the
watchdog timer will expire.
1: disable the receive watchdog.

JCLK Jabber clock
0: cut off transmission after 2.6 ms (100Mbps) or 26 ms
(10Mbps).
1: cut off transmission after 2560 byte-time.

Non-Jabber
0
R/W
0: if jabber expires, re-enable transmit function after 42 ms
(100Mbps) or 420ms (10Mbps).
1: immediately re-enable the transmit function after jabber
expires.

CSR16(offset = 80h), ACSR5 - Assistant CSR5(Status register 2)
31
TEIS Transmit Early Interrupt status
0
RO/LH*
Transmit early interrupt status is set to 1 when TEIE (bit 31 of
CSR17 set) is enabled and the transmitted packet is moved
from descriptors to the TX-FIFO buffer. This bit is cleared by
writing a 1.
30
REIS Receive Early Interrupt Status.
0
RO/LH*
Receive early interrupt status is set to 1 when REIE (CSR17
bit 30) is enabled and the received packet has filled up its first
receive descriptor. This bit is cleared by writing a 1.
29
XIS
Transceiver (XCVR) Interrupt Status. Formed by the logical
0
RO/LH*
OR of XR8 bits 6~0.
28
TDIS Transmit Deferred Interrupt Status.
0
RO/LH*

Reserved
26
PFR PAUSE Frame Received Interrupt Status
1: indicates receipt of a PAUSE frame while the PAUSE
function is enabled.
0
RO/LH*
25~ 23
BET Bus Error Type. This field is valid only when FBE (CSR5 bit
000
RO
13, fatal bus error) is set. There is no interrupt generated by
this field.
000: parity error, 001: master abort, 010: target abort
011, 1xx: reserved
