Master Abort
The PCnet-PCI controller will terminate its cycle with a
Master Abort sequence if
DEVSEL
is not asserted within
4 clocks after
FRAME
is asserted. Master Abort is
treated as a fatal error by the PCnet-PCI controller. The
PCnet-PCI controller will reset all CSR and BCR loca-
tions to their H_RESET values. Any on-going network
activity will be stopped immediately. The PCI configura-
tion registers will not be cleared. RMABORT (bit 13) in
the Status register will be set to indicate that the PCnet-
PCI controller has terminated its transaction with a mas-
ter abort.
