Function
READY
O This pin is used for output of signals indicating
READY for handshaking with the host system. Either
Active High or Active Low can be selected.
READY POLARITY
ID This pin is used for selecting the polarity of the
READY signal.
1: Active High
0: Active Low
SYSTEM BYTE/WORD O This pin is used for output of signals indicating the
CONFIGURATION
system bus width.
The value of bit 5 of the internal register DLCR6 is
reversed.
Low: 8-bit data bus mode
High: 16-bit data bus mode
MODE1
ID This pin is used for setting to general-purpose bus
mode.
• Network interface pins in PC card mode, ISA bus mode, and general-purpose bus mode

COLLISION
LED
OD These pins are used for driving the LED
indicating the occurrence of collisions
(open-drain output).
52 (PC card mode)
LEDL
52 (ISA bus mode)
95 (General-purpose bus mode)
LINK LED
OD These pins are used for driving the LED
indicating the status of the link test (open-
drain output).
These pins are placed in the link-passed
state when the link test is enabled. A Low
level is output to this pin when the link test
is disabled.
When in the power-down or shut-down
mode, these pins enter the high-
impedance state, regardless of the status
of the link test.

indicating transmit-on status (open-drain
output).

RECEIVE LET
OD These pins are used for driving the LED
indicating receive-on status (open-drain
output).
77
TPOPB TWISTED
O These pins are used for output of
78
TPOPA PAIR OUTPUT
differential transmit signals from the built-
79
TPONA
in 10BASE-T transceiver. Preconditioning
80
TPONB
is performed by two output pins and
external filters.
