Enable SVID/SID Write. Default = 0.
Enable byte swapping on control words that the SAR writes. Default = low.
Enable byte swapping on control words of a slave write or read access.
Default = low.
Slave DWORD conversion.
Master Data DWORD conversion.
Master Control DWORD conversion.
NOTE(S):
Set to 0.
Fast Empty Flag mode. Logic low is default on reset.
An 8-bit mask which sets one of a range of values for the size of the PCI
address space. Default=0000000.
Parity Error detection and report enable.
Set to 0.
Master enable. M_EN must be asserted (that is, set to 1) before the
CN8237 can act as master on the PCI bus.
Memory Space enable. MS_EN must be asserted (that is, set to 1) before
the CN8237 address space (registers and memory) can be accessed
across the PCI interface.
I/O Space enable. (Not used.) Set to 0.
00000000 = 16 M
10000000 = 8 M
Set to 1 for normal operation.
