The IEEE1588 protocol supported by Freescale Semiconductors was designed for low-cost implementation in Ethernet networks with simple installation and maintenance.

In the example proposed, the register value is put on the PORTB.

The communication between ENC28J60 and PIC it happens through the interface SPI; this only supports the 0,0 modality and the controller is a slave, so the PIC provides the clock and manages the transmission.

The Ethernet is a protocol of CSMA/CD (Carrier Sense Multiple Access/Collision Detect) type developed in 1973, to the purpose of possession the transmissions on the cable reliable in the moderate traffic conditions.

DsPICDEM.net 1 and DsPICDEM.net 2 Connectivity development boards offer the application developer a basic platform for developing and evaluating both con activity and non-con activity based requirements.

The latest Microchip TCP/IP Stack includes an SSL module which enables secure, encrypted communications between two nodes on an unsecured network.
