W83627EHF/EF, W83627EHG/EG
The output type of the eight VID pins is push-pull, and they drive to 3VCC (3.3V) when configured to
the output mode. The output data can be set in the data register (Logical Device B, CR[F1h], bit 7 ~ 0).
The written data can be read if Configuration Register CR[2Ch], bit 3 is set to “0”.
16. PCI RESET BUFFERS
The W83627EHF/EHG/EF/EG 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 W83627EHF/EHG/EF/EG
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.
