A dedicated protocol generation unit provides the ability to detect validity of data received from a configurable logic block, such as a programmable logic device (PLD). Data valid signaling is provided by the configurable logic block, such that invalid data received from the configurable logic block is replaced with programmable insertion data prior to transmission, while valid data is allowed to be transmitted without replacement. Also, data received by Input/Output (I/O) portions of the dedicated protocol generation unit are compared to programmable data patterns. After a positive comparison, matching data is either truncated and not delivered to the configurable logic block, or the matching data is delivered to the configurable logic block with appropriate data valid signaling.
