Description
Mask for the interrupt Mask Register. This
parameter holds the flags that should be
processed by the d20_check_int() function. The
position of the flag is the same as the COM2002x
Interrupt Mask Register.
Number of the retries for the transmission before
the transmission of a packet is aborted.
Valid values: 0 - 255
If this parameter is set to a “yes” (0x01) value then
the D20 driver will disable the transmitter when
the Excessive NAKs interrupt occurs.
0 = do not disable transmitter
1 = disable transmitter
Specifies whether the write routine in the driver
waits for a write acknowledgment from the
network hardware before returning the status to
the upper layer.
0 - do not wait for the acknowledgement.
1 - wait for the acknowledgement.
Specifies whether the d20_write_packet() will wait
for the transmitter to become available.
0 = do not wait for the TA bit
1 = wait for the TA bit
The number of input buffers is determined by
setting this parameter. The input buffers start at
the Packet RAM page 0.
It is assumed that all the input (receive) buffers
are contiguous.
If the command chaining mode is chosen, this
parameter should be set to 2.
The number of output buffers is determined by
setting this parameter. The output buffers follow
the input buffers in the Packet RAM.
It is assumed that all the output (send) buffers are
contiguous.
If the command chaining mode is selected, this
parameter should be set to 2.
The COM2002x has the ability to accept or send
broadcast messages. Broadcast messages are
delivered to every node connected to the segment
of the physical medium.
0 = reception of broadcast packets is not allowed
1 = reception of broadcast packets is allowed
The COM2002x device has the ability to receive
short and/or long packets. Short packets have up
to 253 data bytes, while long packets have up to
507 data bytes.
0 - short packets only
1 - short and long packets
