Auto/Manual: Determines if the Vivado tool will automatically enable fault tolerance, or if you will specify it manually.

Enable Fault Tolerance Support: When enabled, MicroBlaze protects internal block RAM with parity, and supports error correcting codes (ECC) in LMB block RAM, including exception handling of ECC errors. This prevents a bit flip in block RAM from affecting the processor function.
- If this value is auto-computed (by not overriding it), fault tolerance is automatically enabled in MicroBlaze when ECC is enabled in connected LMB BRAM controllers.
- If fault tolerance is explicitly enabled, the IP integrator tool enables ECC
automatically in connected LMB blokRAM Controllers.
- If fault tolerance is explicitly disabled, ECC in connected LMB block RAM
controllers is not affected.
