Table 134. TX FIFO MAC Threshold Register Ports 0 - 3 ($0x614 – 0x617)

Name	Description	Address	Type1	Default

	MAC threshold for TX FIFO Port 0. The
	default value of 0x1BE represents 446 8-byte
	locations. This equates to 3568 bytes of data. A
	unit entry in this register equates to 8 bytes of
	data. When the amount of data stored in the TX
TX FIFO MAC	FIFO reaches this threshold, data is forwarded	0x614	R/W	0x000001BE
Threshold Port 0	to the MAC core and line-side interfaces for	0x614	R/W	0x000001BE
Threshold Port 0	to the MAC core and line-side interfaces for
	onward transmission. By setting the threshold to
	an appropriate value, the user can configure the
	TX FIFO to operate in a “cut-through” mode
	rather than the default “store and forward”
	operation mode.

	MAC threshold for TX FIFO Port 1. The
	default value of 0x1BE represents 446 8-byte
	locations. This equates to 3568 bytes of data. A
	unit entry in this register equates to 8 bytes of
TX FIFO MAC	data. When the amount of data stored in the TX
TX FIFO MAC	FIFO reaches this threshold, data is forwarded	0x615	R/W	0x000001BE
Threshold Port 1	to the MAC core and line-side interfaces for	0x615	R/W	0x000001BE
Threshold Port 1	to the MAC core and line-side interfaces for
	onward transmission. By setting the threshold to
	an appropriate value, the user can configure the
	TX FIFO to operate in a “cut-through” mode
	rather than the default “store and forward”
	operation mode.

	MAC threshold for TX FIFO Port 2. The
	default value of 0x1BE represents 446 8-byte
	locations. This equates to 3568 bytes of data. A
	unit entry in this register equates to 8 bytes of
TX FIFO MAC	data. When the amount of data stored in the TX
TX FIFO MAC	FIFO reaches this threshold, data is forwarded	0x616	R/W	0x000001BE
Threshold Port 2	to the MAC core and line-side interfaces for	0x616	R/W	0x000001BE
Threshold Port 2	to the MAC core and line-side interfaces for
	onward transmission. By setting the threshold to
	an appropriate value, the user can configure the
	TX FIFO to operate in a “cut-through” mode
	rather than the default “store and forward”
	operation mode.

	MAC threshold for TX FIFO Port 3. The
	default value of 0x1BE represents 446 8-byte
	locations. This equates to 3568 bytes of data. A
	unit entry in this register equates to 8 bytes of
TX FIFO MAC	data. When the amount of data stored in the TX
TX FIFO MAC	FIFO reaches this threshold, data is forwarded	0x617	R/W	0x000001BE
Threshold Port 3	to the MAC core and line-side interfaces for	0x617	R/W	0x000001BE
Threshold Port 3	to the MAC core and line-side interfaces for
	onward transmission. By setting the threshold to
	an appropriate value, the user can configure the
	TX FIFO to operate in a “cut-through” mode
	rather than the default “store and forward”
