Is it possible to keep the UART pin assignments the same between the 32- and 16-bit slave fifos?
Ideally, UART pins stay where they are now (53-56), even in 16-bit slave fifo mode, so long as SPI is disabled.
That is:
32-bit, no spi, uart: UART is 53-56.
16-bit, no spi, uart: UART is 53-56.
16-bit, spi, no uart: SPI is 53-56.
Is this possible?

There is a configuration in the pin list (page 33) which shows the 3 options that you're listing. So I'm little confused as to what your question is?

I saw that too, but it seems that setting the slave fifo on 16-bit mode moves the UART pins whether or not SPI is enabled.
Additionally, the slave fifo application notes document does not have that pin configuration, so there is inconsistency in the documentation.

Hi,
There is a hardware limitation in using configuration 2 (in your list). Please let me know your configuration of interest so that we can discuss possible workarounds if needed.

Hi,
Why I can't use the SPI Interface with Slave Fifo 32 BIt Interface?

It is a hardware limitation.
