100 Page Select 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
.
101 Configuration Mode (AnF) 1
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
parameter can be read and written.
Before loading the application page in remote update
mode, Altera recommends that you set this parameter
to 1. The content of the control register cannot be read
properly if you fail to do so.
