ZHCSS37J may 2009 – january 2021 XIO2001
PRODUCTION DATA
The programming model of the XIO2001 PCI-Express to PCI bridge is compliant to the classic PCI-to-PCI bridge programming model. The PCI configuration map uses the type 1 PCI bridge header.
All bits marked with a are sticky bits and are reset by a global reset ( GRST) or the internally-generated power-on reset. All bits marked with a ☆ are reset by a PCI Express reset ( PERST), a GRST, or the internally-generated power-on reset. The remaining register bits are reset by a PCI Express hot reset, PERST, GRST, or the internally-generated power-on reset.
