Features Run Time Configurable Generate Time Configurable
Even/Odd parity Yes -
Baud rate selection Yes -
Priority based interrupt with configu‐
rable enable
Yes -
Hardware Auto Flow Control (cts_n/
rts_n signals)
Yes Yes
DMA Extra (configurable support for
extra DMA sideband signal)
Yes Yes
Note: When a feature is both Generate time and Run time configurable, the feature must be enabled
during Generate time before Run time configuration can be used. Therefore, turning ON a feature
during Generate time is a prerequisite to enabling/disabling it during run time.
