8.3.1.6 I
2
C Reset
This command configures an Ethernet sub-system reset, if no activity from the Ethernet sub-
system or a possible external application also connected to the I
2
C bus was observed for the
specified amount of time (see Figure 4 and Section 3.8 for I
2
C lines). If enabled, the Ethernet
sub-system or an external application will have to send keep alive signals to the I
2
C bus ad-
dress 0x09 within the specified time period. If the keep alive signals are not regularly received
at this address, the watchdog will reset the Ethernet sub-system.
Changing this configuration disables the watchdog. The feature becomes active, if the watch-
dog is enabled again, and after the MIN_START_TIME has passed.
For normal operation, this value should be set to a value greater than 10 minutes (
600000).
