I am facing problem of failing to generate chip select for CS2, CS3 CS4 & CD5 .(using version 10.4)). In processor expert settings are: 1. BA = 80000000, 90000000, A0000000, B0000000 2. Mask = 0001FFFF, 0001FFFF, 0001FFFF, 0001FFFF, 3. write ptect: disabled 4. Left justified 5. Data port 16 bit( (pointer declared as unsigned short *) 6. Byte enable : disabled 7. No burst modes 8. ALE enabled With this settings for addresses above 64k(0xFFFF) the controller hangs. For similar settings but BA= 60000000 & Mask = 0008FFFF, CS0 working OK. So far I was using memory below 64k, & I didn't notice the issue for last two years
