describes the definition for the FIFOCFG register.
Reserved
Minimum inter packet gap. This sets the minimum number of cycles inserted between back-to-back frames
transmitted over the FIFO interface. The minimum required is 3 cycles if CRCAPP=0 and 7 cycles for 8-bit
interfaces if CRCAPP=1.
Enable reset of FIFO receive function.
0 Do not reset the FIFO receiver.
1 Reset the FIFO receiver for as long as this bit is set.
Enable reset of FIFO transmit function.
0 Do not reset the FIFO transmitter.
1 Reset the FIFO transmitter for as long as this bit is set.
Enable FIFO receive function.
0 Disable reception over the FIFO interface, ignoring data presented to the signals.
1 Enable normal reception over the FIFO interface.
Enable FIFO transmit function.
0 Disable transmission over the FIFO interface.
1 Enable normal transmission over the FIFO interface.
Reserved.
Loopback enable.
0 Do not loopback data in the FIFO interface.
1 Loopback transmitted data to the FIFO receiver rather than outputting transmitted data to signals.
Enable receive flow control. Setting FFC overrides this bit.
0 Do not allow the FIFO receiver to assert link-level flow control if eTSEC requires it.
1 Allow the FIFO receiver to assert link-level flow control if eTSEC requires it. This is the default setting.
Enable transmit flow control.
0 Do not allow the FIFO transmitter to assert link-level flow control if transmit data is unavailable, resulting
1 Allow the FIFO transmitter to assert link-level flow control if transmit data is unavailable and SIGM = 01.
