* Loop configuration changes are delayed until the end of a currently received or transmitted frame at the port.

** The possibility of RX FIFO Size reduction depends on the clock source accuracy of the ESC and of every

connected EtherCAT/Ethernet devices (master, slave, etc.). RX FIFO Size of 7 is sufficient for 100ppm accuracy,

FIFO Size 0 is possible with 25ppm accuracy (frame size of 1518/1522 Byte).

*** IP Core since V3.0.0/V3.00c only
