Hello,
In another topic, I discovered that there was no internal 3-state buffer. So, how should I do it if I have let's say 1 master and n slaves on a bus. The master puts an address, and then can either read or write from the slave.
1 bi-dir bus don't seem like a good choice ... So with a din & dout from the master : No problem for dout, only the masters drivers it. But for din, multiples slaves would like to drive it ...I could use a multiplexer for din but it mayu grow quickly ...
What's the common way of doing this ?
The context is a PCI target core that translates single IO request to request to that internal bus, then different cores expose theirs regs thru it.
