size, sector, and address sizes for the UFM block.
Table 2–3. UFM Array Size
There are 512 locations with 9-bit addressing ranging from 000h to 1FFh. Sector 0
address space is 000h to 0FFh and Sector 1 address space is from 100h to 1FFh. The
data width is up to 16 bits of data. The Quartus II software automatically creates logic
to accommodate smaller read or program data widths. Erasure of the UFM involves
individual sector erasing (that is, one erase of sector 0 and one erase of sector 1 is
required to erase the entire UFM block). Since sector erase is required before a
program or write, having two sectors enables a sector size of data to be left untouched
while the other sector is erased and programmed with new data.
