While the
Pattern to Generate field will accept any value from 0x0000 to 0xFFFF, only the number of bits specified in the
Size field will be used for the PGEN output.
Figure 3-1 shows an example of a PGEN macro-cell configured with the
Pattern to Generate 0xD1F2, but with a
Size of 10, resulting in the lower 10 bits being used and the output pattern of
0x1F2.
