3.3
The NINJA C/CX (ADM6992C/CX) supports three types of data forwarding mode, store & forward mode, modified
and MII cut-through.
3.3.1
The NINJA C/CX (ADM6992C/CX) allows switching between different speed media (e.g. 10BaseX and 100BaseX)
in store & forward mode. The entire received frame will be stored into its packet buffer. The NINJA C/CX
(ADM6992C/CX) checks the length and frame check sequence (FCS) of the received frame to prevent the
forwarding of corrupted packets before forwarding to the destination port. A MAC address filtering process can be
enabled to filter local traffic to improve overall network performance. The maximum packet length is up to 9216
bytes in this mode. The maximum packet length is defined in Bit [13:0] of EEPROM register 03
