R,

rmfifofull[3:0]

When asserted, indicates that rate match

FIFO is full (20 words). Bits 0-3 correspond

to lanes 0-3, respectively. Reading the value

of the

rmfifofull

register clears the bits.

This register is only available in the hard

XAUI implementation
From block: Rate match FIFO.

[3:0]

rmfifoempty[3:0]

When asserted, indicates that the rate match

FIFO is empty (5 words). Bits 0-3

correspond to lanes 0-3, respectively.

Reading the value of the

rmfifoempty

register clears the bits. This register is only

available in the hard XAUI implementation
From block: Rate match FIFO.

[2:0]

R,

phase_comp_fifo_error[2:0]

Indicates a TX phase compensation FIFO

overflow or

underrun

condition on the

corresponding lane. Reading the value of the

phase_comp_fifo_error

register clears the

bits. This register is only available in the

hard XAUI implementation
From block: TX phase compensation FIFO.

0x08a [0]

RW

simulation_flag

Setting this bit to 1 shortens the duration of

reset and loss timer when simulating. Altera

recommends that you keep this bit set

during simulation.

For more information about the individual PCS blocks, refer to the Transceiver Architecture chapters of

the appropriate device handbook.
