24 or 32 For the Quartus II software version 13.1 and onwards:
• Width of 24 or 32 when reading and writing the
start address.
• For active serial devices using 24-bit addressing,
such as EPCS128 or EPCQ128,
PGM[23..2]
corresponds to the upper 22 bits of the 24-bits start
address.
PGM[1..0]
is read as
2'b0
.
• For active serial devices using 32-bit addressing,
such as EPCQ256,
PGM[31..2]
corresponds to the
upper 30 bits of the 32-bits start address.
PGM[1..0]
is read as
2'b0
.
For the Quartus II software version 13.0 and earlier:
• Width of 24 when reading and writing the start
address.
• For Arria II, Stratix III, and Stratix IV devices,
PGM[23..0]
form the 24-bit start address.
• For Arria V, Cyclone V, and Stratix V devices, if
you use active serial devices using 24-bit
addressing, such as EPCS128 or EPCQ128,
PGM[23..0]
corresponds to the 24 bits of the start
address. If you use active serial devices using 32-bit
addressing, such as EPCQ256,
PGM[23..0]
corresponds to the 24 MSB of the start address,
thus the 32 bits start address is
PGM[23..0],8'b0
.

In local update mode, this parameter can only be read.
This parameter is set to 1 in application page and is set
to 0 in factory page. In remote update mode, this
