Name and Function
SMOUT 18 I O This active LOW signal when asserted places the 82595FX into a Power
Down mode The 82595FX will remain in power down mode until SMOUT is
unasserted If this line is unconnected to SMOUT from the system bus it can
be used as an active low output which when a POWER DOWN command is
issued to the 82595FX can be used to power down other external
components (this output function is enabled by configuration)
