Description
Running disparity input. When rdforce is high, the value on this pin is
used as the current running disparity instead of the internally generated
one.
Force running disparity. When high, the rdin value overrides the
internally generated running disparity.
Valid signal. When high, indicates that a valid decoded word is present
on the dataout output.
Data output. This is the 8-bit decoded data or command.
Command output. When high, indicates that the output is a command
byte, not a data byte.
Special K error. Asserted high when an invalid 10-bit word is received.
Running disparity error. When high indicates the running disparity rules
have been violated.
Running disparity output. The current running disparity (after decoding
the word present on the dataout output).
Cascaded Running disparity. Used when decoders are cascaded.

The numbers for the logic elements/logic cells (LEs/LCs) and embedded system blocks/embedded array blocks
(ESBs/EABs) are approximate as November 2001.
f MAX is for non-cascaded encoder/decoder.
