14.5.2 PTP Time Data Register (PTP_TDR), Page 4
This register provides a mechanism for reading and writing the 1588 Time and Trigger Control values. The function of this register
is determined by controls in the PTP_CTL register.
14.5.3 PTP Status Register (PTP_STS), Page 4
This register provides basic status and interrupt control for the PTP 1588 operation.

Time Data:
On Reads, successively returns 16-bit values of the Clock time or Trigger Control
information as selected by controls in the PTP Control Register. Additional reads
beyond the avaliable fields will always return 0.
On Writes, successively stores the 16-bit values of Clock time or Trigger Control
Information as selected by controls in the PTP Control Register.
Reserved: Writes ignored, Read as 0
Transmit Timestamp Ready:
A Transmit Timestamp is available for an outbound PTP Message. This bit will be
cleared upon read of the Transmit Timestamp if no other timestamps are ready.
Receive Timestamp Ready:
A Receive Timestamp is available for an inbound PTP Message. This bit will be
cleared upon read of the Receive Timestamp if no other timestamps are ready.
PTP Trigger Done:
A PTP Trigger has occured. This bit will be cleared upon read. This bit will only
be set if Trigger Notification is turned on for the Trigger through the Trigger
Configuration Registers.
PTP Event Timestamp Ready:
A PTP Event Timestamp is available. This bit will be cleared upon read of the PTP
Event Status Register if no other event timestamps are ready.
Reserved: Writes ignored, Read as 0
Transmit Timestamp Interrupt Enable:
Enable Interrupt on Transmit Timestamp Ready.
Receive Timestamp Interrupt Enable:
Enable Interrupt on Receive Timestamp Ready.
Trigger Interrupt Enable:
Enable Interrupt on Trigger Completion.
Event Interrupt Enable:
Enable Interrupt on Event Timestamp Ready.
