The expansion bus address is captured as a derivative of the RESET_IN_N signal going high. When a
programmable-logic device is used to drive the EX_ADDR signals instead of pull-downs, the signals
must be active until PLL_LOCK goes high.
PLL_LOCK is deasserted immediately when watchdog timer event occurs, or when RESET_IN_N is
asserted, or when PWRON_RST_N is asserted. PLL_LOCK remains deasserted for ~24 ref_clocks after
the watchdog reset is deasserted (internal to the chip). A ref clock time period is 1/CLKIN.

Minimum time required to hold the
PWRON_RST_N at logic 0 state after
stable power has been applied to the
IXP42X product line and IXC1100 control
plane processors.
Minimum time required to hold the
RESET_IN_N at logic 0 state after
PWRON_RST_N has been released to a
logic 1 state. The RESET_IN_N signal
must be held low when the
PWRON_RST_N signal is held low.
Maximum time for PLL_LOCK signal to
drive to logic 1 after RESET_IN_N is
driven to logic 1 state. The boot
sequence does not occur until this period
is complete.
Minimum time for the EX_ADDR signals
to drive the inputs prior to RESET_IN_N
being driven to logic 1 state. This is used
for sampling configuration information.
Minimum/maximum time for the
EX_ADDR signals to drive the inputs prior
to PLL_LOCK being driven to logic 1
