Default Value in
Hardware Mode
Description
Connection established for Serial 1 to Ethernet 1.
Transmit Data enable is not supported and should be
tied high. The user must provide gapped clocks to mask
bits if needed. The Transmit Serial data will output on
the rising edge of TCLKI1-4.
In default hardware mode the Serial Interface
Transmitter is powered up and ready to go.
FCS is set to 16 bits for the HDLC Transmitter.
Transmit inter frame gap is one byte. The value is 7E.
Receive HDLC FCS is set to 16 bits. Receive
scrambling and bit ordering controlled by hardware pins
The receive maximum packet length is set to 2016
bytes not including the HDLC FCS.
Any packets greater than 2016 bytes are rejected.
Receive RDEN enable will not be supported and should
be tied high. The Received data is sampled on the
falling edge and gapped clock is supported.
Any error: Jabber timeout, Loss of carrier, Excessive
deferral, Late collision, Excessive collisions, Under run,
collision, deferred, heartbeat fail will result in resending
of packets
Broadcast frames, Control frames, and Errored packets
are rejected.
The maximum receiver packet size is 2016 bytes
including the MAC FCS. Any packet larger that 2016 is
rejected
Flow control is determined by the AFCS pin.
