Subject: [pci] A problem about pci signals
liqiyue,
You should be able to create a PCI target,
Without using:
GNT#, REQ#, only used by initiator to request bus
LOCK#, used by initiator to form atomic operation
PERR#, SERR# used to report errors, if you have an error
You will have to live with it.
But you will have to implement
STOP# this is how the target requests the master
To stop the current transaction.
PAR The target must drive PAR for read data phases.
Parity is even across AD and C/BE lines, and
held valid for one clock after the last data
Transfer phase.
David
Good Luck
