Bit 0: I/O Window 0 Size
When bit 1 if this register is a ‘0’, this bit determines the width of the data path for I/O Window 0
accesses to the card. When bit 1 is a ‘1’, this bit is ignored.
Bit 1: Auto-Size I/O Window 0
This bit controls the method that the width of the data path for I/O Window 0 accesses to the card is
determined. Note that when this bit is a ‘1’, the -IOIS16 signal (see
