4–32 Chapter 4: Backplane Ethernet 10GBASE-KR PHY IP Core
10GBASE-KR PHY 1GbE Registers
Altera Transceiver PHY IP Core November 2012 Altera Corporation
User Guide
Table 420 describes the 1G/10GbE and 10GBASE-R PCS registers.
10GBASE-KR PHY 1GbE Registers
Table 421 describes the 1GbE PMA registers which allow you to customize the TX
and RX serial data interface.
0x66 [31:0] RO
pma_rx_is_lockedtodata
When asserted, indicates that the RX CDR PLL is locked to
the RX data, and that the RX CDR has changed from LTR
to LTD mode.
0x67 [31:0] RO
pma_rx_is_lockedtoref
When asserted, indicates that the RX CDR PLL is locked to
the reference clock.

Name Description
Table 4–20. 10GBASE-R PCS Registers
address Bit Access Name Description
0x80 31:0 RW
Indirect_addr
Because the PHY implements a single channel, this
register must remain at the default value of 0 to specify
logical channel 0.
0x81
2RW
RCLR_ERRBLK_CNT
Error Block Counter clear register. When set to 1, clears
the
RCLR_ERRBLK_CNT
register. When set to 0, normal
operation continues.
3RW
RCLR_BER_COUNT
BER Counter clear register. When set to 1, clears the
RCLR_BER_COUNT
register. When set to 0, normal
operation continues.
0x82
1RO
HI_BER
High BER status. When set to 1, the PCS is reporting a
high BER. When set to 0, the PCS is not reporting a high
BER.
2RO
BLOCK_LOCK
Block lock status. When set to 1, the PCS is locked to
received blocks. When set to 0, the PCS is not locked to
received blocks.
3RO
TX_FIFO_FULL
TX FIFO full. When set to 1, the
TX_FIFO_FULL
is full.
4RO
RX_FIFO_FULL
RX FIFO full. TX FIFO full. When set to 1, the
RX_FIFO_FULL
is full.
5RO
RX_SYNC_HEAD_ERROR
When set to 1, indicates an RX synchronization error.
6RO
RX_SCRAMBLER_ERROR
When set to 1, indicates an RX scrambler error.
7RO
Rx_DATA_READY
When set to 1, indicates the PCS is ready to accept data.
Table 4–21. 1G/10GbE PMA Registers (Part 1 of 2)
address Bit R/W Name Description
0xA8 0 RW
tx_invpolarity
When set to 1, the TX interface inverts the polarity of the
TX data. Inverted TX data is input to the 8B/10B encoder.
0xA8 1 RW
rx_invpolarity
When set to 1, the RX channels inverts the polarity of the
received data. Inverted RX data is input to the 8B/10B
decoder.
0xA8 2 RW
rx_bitreversal_enable
When set to 1, enables bit reversal on the RX interface. The
RX data is input to the word aligner.
