2.15 Reset to Default Information

This programming guide is for PPAP-3710L-0200 Reset to Default (RST2DFT)

feature.

Pin51 of NS PC87417, GPIO45, is defined as RST2DFT status pin that can be read
out to indicate RST2DFT flag.
The RST2DFT flag is defined as following:

(1) "1" : Normal State
            Two events will set this flag to "1".
            One is "PCI Reset Asserted", the other is "Read SET_RST2DFT I/O port".

(2) "0" : Load Default State.
             The trigger event is by shorting JP1 pin1 and pin2 in a short time and then

released, i.e. making an active pulse/edge.

(JP1 "pin1 and pin2" pin header can be connected to a push button. When

the button has been pressed and released, a trigger event will clear
RST2DFT flag to "0" and System will enter to the Load Default state.
System can start the Load Default process due to RST2DFT flag is "0".)

RST2DFT flag can be polled and read its status periodically.
This flag can be set to "1" by reading the SET_RST2DFT I/O port and back to the

normal state.

SET_RST2DFT I/O port Address is "CDEFh" by BIOS initiation and can be changed by

changing two another I/O port content.

    I/O Port "0F57h" contains SET_RST2DFT I/O port Address [A15..A8].
    I/O Port "0F56h" contains SET_RST2DFT I/O port Address [A7..A0].
    For  example,  SET_RST2DFT  I/O  port  address  is  "CDEFh",  then  I/O  Port  "0F57h"

contains the value "CDh", and I/O Port "0F56h" contains the value "EFh".

The following Assembly code is a sample code to read the RST2DFT flag.
