Initiator support
When an EISA locked access to the PCI is encountered (EISA LOCK asserted) the cycle is propagated to
the PCI Bus as a PCI locked cycle Line Buffers in the PCEB are bypassed The PLOCK signal must be
negated (released) before an EISA agent can be granted the EISA Bus Thus when the PCEB acquires the
PCI Bus on behalf of the EISA agent a PCI LOCKED cycle can be performed if needed
