During configuration, different pages are selected by the PGM[2..0] pins. These pins
are used to select one out of eight pages (or eight system configurations). PGM[2..0]
pins are sampled once before the configuration data is sent to the target PLDs.
Setting the PGM[2..0] pins to select an incorrect page (for example, a page that is
non-existent or a blank page) causes the enhanced configuration device to enter an
erroneous state. The only way to recover from this state is to set the PGM[2..0] pins
to select a valid page and then power cycle the board.
To ensure proper configuration, only set the PGM[2..0]pins to select valid pages.
Within each page, you can store as many configuration files as your system needs.
There is no limitation to the length of a page except for the physical limitation
determined by the size of the flash memory (for example, 0xFFFFFFh for EPC16
devices). However, all pages must be contiguous.
The Convert Programming Files window (Tools menu) in the Quartus II software
allows you to create enhanced configuration device programmer object files (.pof)
and enable the dynamic configuration feature.
Passive parallel asynchronous (PPA) and passive parallel synchronous (PPS)
configuration modes are not supported by enhanced configuration devices. If you
choose one of these modes, the Quartus II software reports an error message when the
.pof is generated.
