The PCI Slave will accept any combination of byte enables during read or
write cycles. During write cycles, a discontinuity (i.e., a 'hole') in the byte
enables forces the PCI Slave to issue a disconnect. During all read cycles,
the PCI Slave returns an entire word of data regardless of the byte enables.
During I/O read cycles, the PCI Slave performs integrity checking of the
byte enables against the address being presented and assert SERR* in the
event there is an error.
