I/O Block Region
MAX II devices feature a single UFM block, which can be used like a serial EEPROM
for storing non-volatile information up to 8,192 bits. The UFM block connects to the
logic array through the MultiTrack interconnect, allowing any LE to interface to the
UFM block.
used to create customer interface or protocol logic to interface the UFM block data
outside of the device. The UFM block offers the following features:
