4.5.2 RESET SEQUENCE
Figure 4-4
STPC, also called warm reset.
The constraints on the strap options and the bus
activities are the same as for the cold reset.
The SYSRSTI# pulse duration must be long
enough to have all the strap options stabilized and
must be adjusted depending on resistor values.

VALID CONFIGURATION
It is mandatory to have a clean reset pulse without
glitches as the STPC could then sample invalid
strap option setting and enter into an umpredicta-
ble mode.
While SYSRSTI# is active, the PCI clock PLL runs
in open loop mode at a speed of few 100’s KHz.
