8B/10B Decoder Enable. This bit enables the 8B/10B decoder logic for the fiber optics
receiver. If the 8B/10B decoder is disabled, no synchronization is locked onto and therefore the
fiber optics ready status is not asserted, and no tokens/cells are pushed into the token/input
fifos. It is generally a good idea to program the 8B/10B decoder lookup table before the 8B/10B
decoder is enabled.
