Доброго дня коллеги! Не мог бы кто подсказать как ведут себя выходы(в каком состаянии находятся???) циклона 2 в интервале времени от подачи питания до окончания загрузки ПЛИС из флеш? И можно ли управлять этим процессом???
Заранее благодарен.
Cyclone II Device Handbook:
Upon power-up, the Cyclone II device goes through a POR. During POR,
the device resets, holds nSTATUS and CONF_DONE low, and tri-states all
user I/O pins. After POR, which typically lasts 100 ms, the Cyclone II
device releases nSTATUS and enters configuration mode when the
external 10-kΩ resistor pulls the nSTATUS pin high. Once the FPGA
successfully exits POR, all user I/O pins continue to be tri-stated.
Cyclone II devices have weak pull-up resistors on the user I/O pins
which are on before and during configuration.
