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: if jabber expires, re-enable transmit function
after 42 ms (100Mbps) or 420ms (10Mbps).
1: immediately re-enable the transmit function
after jabber expires.
Jabber disable
1: disable transmit jabber function
Transmit early interrupt status
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.
Receive early interrupt status.
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.
Transceiver (XCVR) interrupt status. Formed by
the logical OR of XR8 bits 6~0.
Transmit deferred interrupt status.
Reserved
PAUSE frame received interrupt status.
1: indicates receipt of a PAUSE frame while the
PAUSE function is enabled.
Bus error type. This field is valid only when FBE
(CSR5 bit 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
