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.
UFM block and interface signals. The logic array is 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:
