Figure 143 shows the internal architecture of IEEE 1588-2008 hardware assist
implementation in the EP80579. It also shows the various internal registers within the
block, such as the System Time Clock register, which contains the system time used for
time stamping and triggering events that can be used to drive outputs. Examples of
these conditions are:
• expiration of the Target Time or Auxiliary Target Time register
• PPS Compare register greater or equal to the system time clock
• Ethernet or CAN message detect
• edge detect of Auxiliary Master/Slave inputs
All of the conditions shown above generate interrupts, which can be serviced
immediately for time-critical applications.
The above features require software support, if you intend to use these features, see
the Intel
