2.7.2. Data Byte Output

In M10K blocks, the corresponding masked data byte output appears as a “don’t care” value.

In MLABs, when you de-assert a byte-enable bit during a write cycle, the corresponding data byte output appears as either a “don't care” value or the current data at that location. You can control the output value for the masked byte in the MLABs by using the Intel® Quartus® Prime software.
