Chip enable vs chip select
WebWhen chip select is asserted, the chip internally performs the access, and only the final output drivers are disabled by deasserting output enable. This can be done while the bus … Web\$\begingroup\$ I guess the statement is incorrect because you can use I/O pins as CS. But if you do that you will have a segmented address space or a very complicated and slow way to work around it: e.g. when processor tries to access to a currently non-selected chip, MMU will intercept the access and generate a segfault, the processor handles the segfault by …
