oscillator. The dedicated circuitry uses this internally for its read and program
operations. This oscillator's divide by 4 output can drive out of the UFM block as a
logic interface clock source or for general-purpose logic clocking. The typical OSC
output signal frequency ranges from 3.3 to 5.5 MHz, and its exact frequency of
operation is not programmable.
The UFM block’s dedicated circuitry automatically generates the necessary internal
program and erase algorithm once the PROGRAM or ERASE input signals have been
asserted. The PROGRAM or ERASE signal must be asserted until the busy signal
deasserts, indicating the UFM internal program or erase operation has completed. The
UFM block also supports JTAG as the interface for programming and/or reading.
For more information about programming and erasing the UFM block, refer to the

The UFM block supports standard read or stream read operations. The stream read is
supported with an auto-increment address feature. Deasserting the ARSHIFT signal
while clocking the ARCLK signal increments the address register value to read
consecutive locations from the UFM array.
The UFM block supports a serial interface with serial address and data signals. The
internal shift registers within the UFM block for address and data are 9 bits and 16 bits
wide, respectively. The Quartus II software automatically generates interface logic in
LEs for a parallel address and data interface to the UFM block. Other standard
protocol interfaces such as SPI are also automatically generated in LE logic by the
Quartus II software.
For more information about the UFM interface signals and the Quartus II LE-based
alternate interfaces, refer to the
the MAX II Device Handbook.
The UFM block is a small partition of the flash memory that contains the CFM block,
as shown in
located on the left side of the device adjacent to the left most LAB column. The UFM
block for the EPM570, EPM1270, and EPM2210 devices is located at the bottom left of
the device. The UFM input and output signals interface to all types of interconnects
(R4 interconnect, C4 interconnect, and DirectLink interconnect to/from adjacent LAB
rows). The UFM signals can also be driven from global clocks, GCLK[3..0]. The
interface region for the EPM240 device is shown in
for EPM570, EPM1270, and EPM2210 devices are shown in
