22.2.33 Memory Space Base Register (PCIMBR)

The memory space base register (PCIMBR) specifies the most significant 8 bits of the address of

the PCI memory space when performing a memory read/write operation using PIO transfers. It

also specifies locked transfers. This 32-bit read/write register can be accessed from the PP bus.

All bits of the PCIMBR 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 memory 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.
