11.7 FCR – Flooding Control Register
• Access: parallel interface and I²C, Read/Write
• Address: h03
Bits [3:0] U2MR
Bits [6:4] TimeBase
Bit 7
USE_TOS
Maximum number of flooded
frames allowed within any time
interval indicated by TimeBase
bits (violations are discarded)
000 = 100 µs 001 = 200 µs
010 = 400 µs 011 = 800 µs
100 = 1.6 µs 101 = 3.2 µs
110 = 6.4 µs 111 = 100 µs
Use TOS instead of VLAN
priority for IP packet
(Default = 8)
(Default = 000)
(Default = 0)
