Software Support for UFM Block

The UFM block’s internal oscillator is always running when the altufm_parallel
magafunction is instantiated for read/write interface. The UFM block’s internal
oscillator is disabled when the altufm_parallel megafunction is instantiated for read
only interface.
None (Altera Serial Interface)
None means using the dedicated UFM serial interface. The built-in UFM interface
uses 13 pins for the communication. The functional description of the 13 pins are
described in Table 9–4 on page 9–3. You can produce your own interface design to
communicate to/from the dedicated UFM interface and implement it in the logic
array.
Instantiating None Using Quartus II altufm Megafunction
Figure 9–43 shows the altufm megafunction symbol for None instantiation in the
Quartus II software.
