Asserted by the downstream module if it is able to accept data.
Marks the start of the outgoing result group. If '1', a result corresponding to
channel 0 is output.
Asserted by the MegaCore function when there is valid data to output.
This signal is available when the variable rate change factor option is enabled, and
can be used to change the decimation/interpolation rate during run time. It has the
