This megafunction is in the I/O folder on page 2a of the MegaWizard Plug-In
Manager. On page 3 of the MAX II/MAX V Oscillator megafunction, you have an
option to choose to simulate the OSC output port at its maximum or minimum
frequency during the design simulation. The frequency chosen is only used as a
timing parameter simulation and does not affect the real MAX V device OSC output
frequency.
There are three different modes for the UFM block:

During program mode, address and data can be loaded concurrently. You can
manipulate the UFM interface controls as necessary to implement the specific
protocol provided the UFM timing specifications are met.
Figure 7–8
For program mode
signals can be asserted anytime after the address register and data register have been
loaded. Do not assert the READ, PROGRAM, and ERASE signals or shift data and address
into the UFM after entering the real-time ISP mode. You can use the RTP_BUSY signal to
detect the beginning and end of real-time ISP operation and generate control logic to
stop all UFM port operations. This user-generated control logic is only necessary for
the ALTUFM_NONE megafunction, which provides no auto-generated logic. The
other interfaces for the ALTUFM megafunction (ALTUFM_PARALLEL,
ALTUFM_SPI, ALTUFM_I2C) contain control logic to automatically monitor the
RTP_BUSY signal and will cease operations to the UFM when a real-time ISP operation
is in progress.
You can program the UFM or CFM block independently without overwriting the
other block, which is not programmed. The Quartus II programmer provides the
options to program the UFM and CFM blocks individually or together (the entire
MAX V Device).
For guidelines about using ISP and real-time ISP while using the UFM block within
your design, refer to

timing parameters listed in this chapter, refer to the
