DescriptionRequiredTypeParameter Name
Specifies whether the write-protect port protects
only the upper half of the UFM block or the entire
UFM block from writes/erases. Values are FULL
and UPPER_HALF. If omitted, the default is
FULL.
NoStringMEM_PROTECT
Specifies the memory size. Values are 1K, 2K, and
4K. If omitted, the default is 4K.
YesStringMEMORY_SIZE
Specifies the oscillator frequency for the user flash
memory. Values are 180000 ps (5.56 MHz) or
300000 ps (3.33 MHz). If omitted, the default is
180000 ps. The OSC_FREQUENCY setting
controls the oscillator frequency during
simulations and does not affect the device’s
oscillator frequency, which can range from
3.33 MHz (300000 ps) to 5.56 MHz (180000 ps).
(2)
NoIntegerOSC_FREQUENCY
Specifies the write mode. If omitted, the default
is SINGLE_BYTE.
NoStringWRITE_MODE
Allows you to assign Altera-specific parameters
in VHDL Design Files (.vhd). The default is
UNUSED.
NoStringLPM_HINT
Identifies the library of parameterized modules
(LPM) entity name in VHDL Design Files.
NoStringLPM_TYPE
Notes to Table 2–7:
1. This parameter is used for modeling and behavioral simulation purposes
2. This parameter is used for simulation purposes only.

If the osc port is specified, the
oscena port is required. (1)
Oscillator output.Noosc
When the rtpbusy is high, it
cannot be used. (1)
Busy signal that indicates when in
system configuration is using flash
memory.
