processor in a reset state. The LSIFC929XL maintains
this state until the PCI host clears both the Flash Bad
Signature and DisARM bits.
Reset History
5
The LSIFC929XL sets this bit if it experiences a Power-
On Reset (POR), PCI Reset, or TestReset/. A host driver
can clear this bit to help coordinate recovery between
multiple driver instances in a multifunction PCI
implementation.
Diagnostic Read/Write Enable
4
Setting this bit enables access to the Diagnostic
registers.
TTL Interrupt
3
Setting this bit congures PCI INTA/ as a TTL output.
Clearing this bit congures PCI INTA/ as an open-drain
output. Use this bit for test purposes only.
Reset Adapter
2
Setting this write-only bit causes a hard reset within the
LSIFC929XL. The bit self-clears after eight PCI clock
periods. After deasserting this bit, the IOP ARM
processor executes from its default reset vector.
DisARM
1
Setting this bit disables the IOP ARM processor.
Diagnostic Memory Enable
0
Setting this bit enables diagnostic memory accesses
through PCI Memory Space [1]. Clearing this bit disables
diagnostic memory accesses to PCI Memory Space [1]
and returns 0xFFFF on reads.
