Disconnect When Locked
When the PCnet-PCI II controller is locked by one
master and another master tries to access the control-
ler, the device will disconnect the access. When the
PCnet-PCI II controller is in the locked state and it sees
LOCK asserted together with FRAME, it knows that

another master tried to access it. The PCnet-PCI II con-
troller will respond to the access by asserting STOP to-
gether with DEVSEL while driving TRDY high, thereby
disconnecting the cycle. STOP will stay asserted until
the other master removes FRAME.
