CNTR_RX_STATUS

• Bit [1]: Indicates that the RX statistics registers are

paused (while

CNTR_RX_CONFIG[2]

is asserted) .

• Bit [0]: Indicates the presence of at least one parity

error in the RX statistics counters.

Bits [31:2] are Reserved.

RxOctetsOK_LO

Number of received payload bytes in frames with no FCS,

undersized, oversized, or payload length errors. This

register is compliant with section 5.2.1.14 of the IEEE

Standard 802.3-2008.
Instead of an increment vector, this register corresponds to

the signals

rx_inc_octetsOK[15:0]

and

rx_inc_

1588 PTP Registers

The 1588 PTP registers together with the 1588 PTP signals process and provide Precision Time Protocol

(PTP) timestamp information as defined in the IEEE 1588-2008 Precision Clock Synchronization Protocol

for Networked Measurement and Control Systems Standard. The 1588 PTP module provides you the

support to implement the 1588 Precision Time Protocol in your design.
