ISACSR6 controls the func-
tion(s)
displays. Multiple functions can
be simultaneously enabled on
this LED pin. The LED display will
indicate the logical OR of the en-
abled
defaults to twisted pair MAU Re-
ceive Polarity (RCVPOL) with
pulse stretcher enabled (PSE =
1) and is fully programmable.
Indicates
stretched) state of the function(s)
generated. Read only.
Reserved locations. Read and
written as zero.
Pulse Stretcher Enable. Extends
the LED illumination for each en-
abled function occurrence.
0 is disabled, 1 is enabled.
Reserved locations. Read and
written as zero.
Enable Transmit Status Signal.
Indicates PCnet-ISA controller
transmit activity .
0 disables the signal, 1 enables
the signal.
Enable Receive Polarity Signal.
Enables LED pin assertion when
receive polarity is correct on the
10BASE-T port. Clearing the bit
indicates this function is to
be ignored.
Enable Receive Status Signal.
Indicates receive activity on the
network.
0 disables the signal, 1 enables
the signal.
Enable Jabber Signal. Indicates
the PCnet-ISA controller is jab-
bering on the network.
0 disables the signal, 1 enables
the signal.
Enable Collision Signal. Indi-
cates collision activity on the
network.
