How can the data in endpoint 0 exchange with external processor? Can it share the FD15:0 with endpoint 2,4,6,8 when 68013 is in slave FIFO mode?
I know the data in endpoint 0 can be exchanged with external processor when the FD15:0 is I/O port.
I also know it can when in GPIF mode.
But I only want to do that in the slave FIFO mode. For my system is based on the slave FIFO mode.
Please tell me if somebody know that. Thanks a lot.
EP0 doesn't provide FIFO interface to external processor. Why do you want to implement data transfer through EP0??.
You could try copying EP0 data to any of EP2, EP4, EP6 or EP8 endpoints and then transfer to external processor.
