Ethernet Packet Generator Control 1

The EPG control register provides access to and control of various aspects of the EPG testing feature. There are two
separate EPG control registers. The following table shows the settings available in the first register.

Table 3.34 EPG Control Register 1, Address 29E1 (0x1D)

Bit Name
15 EPG enable
14 EPG run or stop
13 Transmission duration
12:11 Packet length
10 Interpacket gap
9:6 Destination address
5:2 Source address
1 Payload type
0 Bad frame check sequence
(FCS) generation
The following information applies to the EPG control number 1:
• Do not run the EPG when the GbE-PHY is connected to a live network.
• bit 29E1.13 (continuous EPG mode control): When enabled, this mode causes the device to send continuous packets.
When disabled, the device continues to send packets only until it reaches the next 10,000-packet increment mark. It
then ceases to send packets.
• The 6-byte destination address in bits 9:6 is assigned one of 16 addresses in the range of 0xFF FF FF FF FF F0
through 0xFF FF FF FF FF FF.
• The 6-byte source address in bits 5:2 is assigned one of 16 addresses in the range of 0xFF FF FF FF FF F0 through
0xFF FF FF FF FF FF.
• If any of bits 13:0 are changed while the EPG is running (bit 14 is set to 1), bit 14 must be cleared and then set back
to 1 for the change to take effect and to restart the EPG.
