Description
Scrambler Mode, set to enable scrambler function and the MII/SYM port transmit and receive
scrambled symbols.
Set to enable PCS functions and the MII/SYM port operates in symbol mode. CSR6<18>
must be set in order to operate in MII/ SYM port.
Transmit Threshold Mode, set for 10Mbps and reset for 100Mbps.
Store and Forward, when set, transmission starts only if a full packet is in transmit FIFO; the
threshold values defined in CSR6<15:14> is ignored
Heartbeat Disable, set to disable SQE function in 10Mbps mode. This bit should be set in
MII/SYM port.
Port Select, set for MII/SYM port. A software reset does not affect this bit.
Collision Offset Enable, set to enable a modified backoff algorithm during low collision sit-
uation, reset for normal backoff algorithm.
Threshold Control Bits, these bits control the selected threshold level for PMAC's transmit
FIFO; transmission starts when frame size within the transmit FIFO is larger than the selected
threshold. Full frames with a length less than the threshold are also transmitted.
Value after reset is "E0000040"h
