Thank you very much. I found the (other) bug in the meantime

When writing to 8 bit data bus, WRL is activated for both even and odd
address writes. This information can be found in the data sheet.

We use an infineon c167cs with 16 bit ram+flash and some 8 bit peripherals. The
processor has the pins wrl and wrh/bhe. If we choose wrl+wrh to control the 16
bit RAM (bit 7=wrcfg=1 in syscon0), the 8 bit peripherals cannot be written on
odd adresses (it seems). Do we have to put in some external logic or is there a
configuration trick to use wrl on all adresses in 8 bit windows? I could not
find any associated bit in the buscons.
thanks
