Watchdog Timeout Register
| WTO | Watchdog Timeout When the PWE bit is set and the ETH_MAC_CONFIGURATION[WD] bit is reset, this field is used as watchdog timeout for a received packet. If the length of a received packet exceeds the value of this field, such packet is terminated and declared as an error packet. Note: When the PWE bit is set, the value in this field should be more than 1,522 (0x5F2). Otherwise, the IEEE 802.3-specified valid tagged packets are declared as error packets and then dropped. 0 (Val_0x0): 2KB 1 (Val_0x1): 3KB 2 (Val_0x2): 4KB 3 (Val_0x3): 5KB 4 (Val_0x4): 6KB 5 (Val_0x5): 7KB 6 (Val_0x6): 8KB 7 (Val_0x7): 9KB 8 (Val_0x8): 10KB 9 (Val_0x9): 11KB 10 (Val_0xA): 12KB 11 (Val_0xB): 13KB 12 (Val_0xC): 14KB 13 (Val_0xD): 15KB 14 (Val_0xE): 16383 bytes |
| PWE | Programmable Watchdog Enable When this bit is set and the ETH_MAC_CONFIGURATION[WD] bit is reset, the WTO field is used as watchdog timeout for a received packet. When this bit is cleared, the watchdog timeout for a received packet is controlled by setting of the ETH_MAC_CONFIGURATION[WD] and ETH_MAC_CONFIGURATION[JE] bits. 0 (Val_0x0): Programmable watchdog is disabled 1 (Val_0x1): Programmable watchdog is enabled |
