Frame Checker Odd Nibble Frame Count Register

Device Address: 0x1F; Register Address: 0x8010, Reset: 0x0000, Name: FC_ODD_CNT

This register is a latched copy of the odd nibble frame register. This register is a count of received frames with an odd number of nibbles in the

frame. When the receive error counter (RX_ERR_CNT) is read, the odd nibble frame counter register is latched, which ensures that the odd

nibble frame count and the receive frame count are synchronized.

Frame Checker Odd Preamble Packet Count Register

Device Address: 0x1F; Register Address: 0x8011, Reset: 0x0000, Name: FC_ODD_PRE_CNT

This register is a latched copy of the odd preamble packet counter register. This register is a count of received packets with an odd number of

nibbles in the preamble. When the receive error counter (RX_ERR_CNT) is read, the odd preamble packet counter register is latched, which

ensures that the odd preamble packet count and the receive frame count are synchronized.

Frame Checker False Carrier Count Register

Device Address: 0x1F; Register Address: 0x8013, Reset: 0x0000, Name: FC_FALSE_CARRIER_CNT

This register is a latched copy of the false carrier events counter register. This is a count of the number of times the bad SSD state is entered.

When the receive error counter (RX_ERR_CNT) is read, the false carrier events counter register is latched, which ensures that the false carrier

events count and the receive frame count are synchronized.

Frame Generator Enable Register

Device Address: 0x1F; Register Address: 0x8020, Reset: 0x0000, Name: FG_EN

This register is used to enable the frame generator. When the frame generator is enabled, the source of data for the PHY comes from the frame

generator and not the MAC interface. To use the frame generator, the diagnostic clock must also be enabled (DIAG_CLK_EN).
