GLPCI_REGCONF[x] Bit Descriptions (Continued)
Description
Region Space Indicator.
0: Memory space.
1: I/O space.
Base of Region. For memory use [31:12] as base of address bits [31:12].
For I/O use [31:14] as base of address bits [19:2]. (Note 1)
Reserved (Read Only). Returns 0.
Prefetchable. If region is memory and this bit is set, it indicates a prefetechable memory
region. Reads to this region have no side-effects. If region is I/O and this bit is set, post all
I/O writes to this region.
Reserved (Read Only). Returns 0.
Retry/Hold. Defines whether GLPCI_SB PCI slave generates a retry condition or holds
the PCI bus until cycle completion. Note that even if hold is selected, the cycle will be ter-
minated if initial latency time-out is reached.
0: Retry.
1: Hold.
Region Enable. Set to 1 to enable access to this region.
