5.4 Local Software Reset

The PCI9030 Local Reset Output LRESETo# is used to reset the on board local logic.

The PCI9030 local reset is active during PCI reset or if the PCI Adapter Software Reset bit is set in the
PCI9030 local configuration register CNTRL (offset 0x50).

CNTRL[30] PCI Adapter Software Reset:

Value of 1 resets the PCI9030 and issues a reset to the Local Bus (LRESETo# asserted). The
PCI9030 remains in this reset condition until the PCI Host clears this bit. The contents of the PCI9030
PCI and Local Configuration Registers are not reset. The PCI9030 PCI Interface is not reset.
