Description

Type

Default

Port N Egress Timestamp for Sync Frame Interrupt Enable

(TS_SYNC_INT_ENB)

When this bit is set to 1, the egress timestamp interrupt from Port N for the

Sync frame is enabled.

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 Enable bit in the Port Interrupt Mask

R/W

Port N Egress Timestamp for Pdelay_Req and Delay_Req Frames

Interrupt Enable (TS_PDLY_REQ_INT_ENB)

When this bit is set to 1, the egress timestamp interrupt from Port N for the

Pdelay_Req and Delay_Req frames is enabled.

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 Enable bit in the Port Interrupt Mask

R/W

Port N Egress Timestamp for Pdelay_Resp Frame Interrupt Enable

(TS_PDLY_RESP_INT_ENB)

When this bit is set to 1, the egress timestamp interrupt from Port N for the

Pdelay_Resp frame is enabled.

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 Enable bit in the Port Interrupt Mask
