W83627DHG
19. PCI RESET BUFFERS
The W83627DHG has five copies of LRESET# output buffers. LRESET# is LPC Interface Reset, to
which PCI Reset is connected. The five copies of LRESET# in the W83627DHG are designated
RSTOUT0#, RSTOUT1#, RSTOUT2#, RSTOUT3# and RSTOUT4#. All of them are powered by a
3VSB power.
RSTOUT0# is an open-drain output buffer of LRESET#. This signal needs an external pulled-up
resistor of 3.3V or 5V.
RSTOUT1#, RSTOUT2#, RSTOUT3# and RSTOUT4# are push-pull output buffers of LRESET#. Each
of them outputs 3.3V, voltage and the state is low when the 3VSB power is the only power source.
