Port N Egress Timestamp for Sync Frame Interrupt Status

(TS_SYNC_INT_STATUS)

When this bit is set to 1, it indicates that the egress timestamp is available

from Port N for the Sync frame.

This bit is logical OR’ed together with the rest of the bits in this register and

the output is shown as the PTP Interrupt Status bit in the Port Interrupt Status

R/W1C

Port N Egress Timestamp for Pdelay_Req and Delay_Req Frames

Interrupt Status (TS_PDLY_REQ_INT_STATUS)

When this bit is set to 1, it indicates that the egress timestamp is available

from Port N for the Pdelay_Req and Delay_Req frames.

This bit is logical OR’ed together with the rest of the bits in this register and

the output is shown as the PTP Interrupt Status bit in the Port Interrupt Status

R/W1C

Port N Egress Timestamp for Pdelay_Resp Frame Interrupt Status

(TS_PDLY_RESP_INT_STATUS)

When this bit is set to 1, it indicates that the egress timestamp is available

from Port N for the Pdelay_Resp frame.

This bit is logical OR’ed together with the rest of the bits in this register and

the output is shown as the PTP Interrupt Status bit in the Port Interrupt Status
