8.1.3
This section describes the registers which are located on the configuration bus II (see
also These registers can be accessed either from PCI bus via the internal bus bridge or
from the local bus side.
Note: Since the local bus is 16-bit wide and the PCI bus is 32-bit wide, the upper 16 bit
Note: Please note that read accesses to local bus registers via PCI bus and therefore

the internal bus bridge may result in latencies which exceed the 16 clock rule of
PCI specification. Exceeding the 16 clock rule results in target initiated retry on
PCI bus. In this case the read cycle needs to be repeated.
