7 to 0 STARTA(15:8)
High-order address bits used to determine the start address of an I/O address window.
Remark Address bits 25 to 16 of an I/O window address are fixed to 0. Therefore, an I/O window is always
mapped to the address space between 0x1400 0000 and 0x1400 FFFF, which is the first 64 KB of the
ISA-IO space.
