22.2.34 I/O Space Base Register (PCIIOBR)
The I/O space base register (PCIIOBR) species the most significant 14 bits of the address of the
PCI I/O space when performing I/O read and I/O write operations by PIO transfer. It also specifies
locked transfers. This 32-bit read/write register can be accessed from the PP bus.
All bits of the PCII0BR register are initialized to 0 at a power-on reset. They are not initialized at a
software reset.
Setting bit 0 (LOCK) to 1 locks the I/O space for PIO transfers while the bit remains set. A locked
transfer consists of the combined read and write operations. Do not attempt to perform other PIO
transfers during the locked combination of read and write operations.
