PADR[15:0]. Undefined until in-
itialized either automatically by
loading the initialization block or
directly by an I/O write to this
register. The PADR bits are
transmitted PADR[0] first and
PADR[47] last.

This register’s fields are loaded
during the PCnet-ISA controller
initialization routine with the cor-
responding Initialization Block
values. The register can also be
loaded directly by an I/O write.
Activating the RESET pin clears
all bits of CSR15 to zero.

Promiscuous Mode.
When PROM = “1”, all incoming
receive frames are accepted.
Read/write accessible only when
STOP bit is set.
DisableReceive Broadcast
set, disables the PCnet-ISA con-
troller from responding to broad-
cast messages. Used for proto-
cols that do not support broad-
cast addressing, except as a
function of multicast. DRCVBC is
cleared by activation of the
RESET pin (broadcast mes-
sages will be received).
Read/write accessible only when
STOP bit is set.
Disable Receive Physical Ad-
dress. When set, the physical
address detection (Station or
node ID) of the PCnet-ISA con-
troller will be disabled. Frames
addressed to the nodes individ-
ual physical address will not be
recognized (although the frame
may be accepted by the EADI
mechanism).
Read/write accessible only when
STOP bit is set.

DLNKTST = “1”, monitoring of
Link Pulses is disabled. When
DLNKTST = “0”, monitoring of
Link Pulses is enabled. This bit
only has meaning when the

sal
Likewise, when DAPC = “0”, the
