Description

Type

Default

15:0

PTP Port N TX Latency in Nanoseconds (PTP_TX_LATENCY[15:0])

This field is used to set the fixed transmit delay value from the port N TX time-

stamp to the wire. The default value is 45ns.

R/W

Description

Type

Default

PTP Port N Asymmetry Correction Sign Bit (PTP_ASYM_COR_SIGN)

1 = The magnitude in the PTP_ASM_COR field of this register is negative.

0 = The magnitude in the PTP_ASM_COR field of this register is positive.

R/W

14:0

PTP Port N Asymmetry Correction in Nanoseconds (PTP_ASYM_COR)

This field is used to set the fixed asymmetry value to add in the correction

field for ingress Sync and Pdelay_Resp or to subtract from the correction field

for egress Delay_Req and Pdelay_Req.

Type

Default

15:0

PTP Port N Egress Timestamp for Pdelay_Req and Delay_Req in

Nanoseconds (XDLY_REQ_TS[31:16])

This field contains the Port N egress timestamp high-word value for Pde-

lay_Req and Delay_Req frames in nanoseconds.

0x0000

Address:

0xNC0A - 0xNC0B

Default

15:0

PTP Port N Egress Timestamp for Pdelay_Req and Delay_Req in

Nanoseconds (XDLY_REQ_TS[15:0])

This field contains the Port N egress timestamp low-word value for Pde-

lay_Req and Delay_Req frames in nanoseconds.
