Bit
Function
Type
Description
Controls response to I/O access on the primary interface
0: ignore I/O transactions on the primary interface
1: enable response to I/O transactions on the primary interface
Reset to 0
Controls response to memory accesses on the primary interface
0: ignore memory transactions on the primary interface
1: enable response to memory transactions on the primary interface
Reset to 0
Controls ability to operate as a bus master on the primary interface
0: do not initiate memory or I/O transactions on the primary
interface and disable response to memory and I/O transactions on
secondary 1 interface
1: enables PI7C7300A to operate as a master on the primary
interfaces for memory and I/O transactions forwarded from the
secondary interface
Reset to 0
No special cycles defined.
Bit is defined as read only and returns 0 when read
Memory write and invalidate not supported.
Bit is implemented as read only and returns 0 when read (unless
forwarding a transaction for another master)
Controls response to VGA compatible palette accesses
0: ignore VGA palette accesses on the primary
1: enable positive decoding response to VGA palette writes on the
primary interface with I/O address bits AD[9:0] equal to 3C6h,
3C8h, and 3C9h (inclusive of ISA alias; AD[15:10] are not decoded
and may be any value)
