About the Master termination when the Target is waiting
My name is Makoto Takebe from KOMATSU Ltd. in Japan. I am currently
responsible for the development of our PCI I/F Card. The reason I am writing
to you is because I have a few opinions in the case of the title.And I am
hoping you to judge and correct my opinions. Your assistance will be much
appreciated.
Here are my opinions:
About the Master termination when the Target is waiting
1 By PCI convention, if the Master terminate when the Target is waiting,
the data phase is defined as data transfer error.
2 Target must always detect the Master termination even though during waiting
period.
3 Target must terminate the transaction even though during waiting period.
4 After data transfer error transaction, PCI system also must operates as
usual. (PCI system must not hung up after data transfer error transaction)
5 I think even though the Master terminate read cycle when the Target is
waiting,if later the Master operate the read cycle, finally the data which
could not transfered before is transfered correctlly at this time .
I think it would happen when the case as above.
Sincerely
