Reset Timings
The IXP45X/IXP46X network processors can be reset in any of the following three
modes:
Normally, a Cold Reset is executed each time power is initially applied to the board, a
Warm Reset is executed when it is only intended to reset the IXP45X/IXP46X network
processors, and a Soft Reset is executed by the watchdog timer.
Cold Reset
A Cold Reset condition is when the network processor is initially powered-up and has
successfully come out of the Reset. During this state all internal modules and registers
are set to the initial default state. To successfully come out of reset, two things must
