(100 Mbps)
A non-back-to-back Transmit IPG is determined by the following formula:
The difference in values between
asynchronous nature of the Carrier Sense (CRS). The CRS must undergo a 2-clock
synchronization before the internal Tx state machine detects it. This synchronization
equates to a 6-clock intrinsic delay between packets instead of the 3-clock intrinsic delay
in the back-to-back packet mode. More information covering this topic is found in the
IEEE 802.3/4.2.3.2.1 Carrier Deference section.
EMAC Interpacket Gap Register
The EMAC Interpacket Gap (IPG) is a programmable field representing the IPG between
back-to-back packets. It is the IPG parameter used in FULL-DUPLEX and HALF-
DUPLEX modes between back-to-back packets. Set this field to the appropriate number
of IPG bytes. The default setting of
