The maximum voltage drop across the diode is 350mV.
See Figure 13.25 to Figure 13.28 in the “Timing Diagrams” section.
IDE Reset Output Pin
nIDE_RST is an open drain buffered copy of nPCI_RESET. This signal requires an external 1kohm pull-up
to VCC5V.
This signal will be low when VCC5V=0 since it is externally pulled up to VCC5V.
See Table 13.1 for nIDE_RSTDRV timing.
PCI Reset Output Pins
The nPCIRST_OUT is 3.3V buffered copy of nPCI_RESET. The nPCIRST_OUT2 is 3.3V buffered copy of
nPCI_RESET.
The nPCIRST_OUT and nPCIRST_OUT2 signals will be low when VCC=0.
