I am using MK66FN2M0VLQ18 microcontroller. By this controller, I am interfacing external memory(MIL-STD1553) using flexbus module. if I use CS0(pin No 128) it is working fine but I want to use CS1(pin No 127) with this configuration it is not working. Can you explain how to use CS1 for accessing external memory module by flexbus
waiting for your suggestions.
