Honored ContributorHello,
I have lan91c111 and cfi-flash component. They share their address and data lines but use different pins. So how can I connect them to the pin. By multiple assignment of the same signal to different pins?
Honored ContributorIf the address and data lines are seperate interfaces on your PCB then I recommend you keep things simple and use two tri-state bridges and connect each device to only one bridge (If you have 5.0 installed, look at the 2c35 standard or full featured designs, they have one bridge for ethernet and flash, and a second one for SSRAM since SSRAM has it's own bus). The bridge assumes that if you put multiple slaves on it that they have a shared address and data bus (that's what caused those signals to be shared by the interface). Then just assign them to pins like you would normally do.
Honored ContributorThat's exactly what I need! Thank you!
