" key before becoming active. Once the initiated, the cards transition to
" the SLEEP state.

" --------------------
" A card wakes up with its Card Select Number (CSN) set to zero. Once a card
" is uniquely isolated, it is assigned a non-zero CSN identifier.
" Cards that have not been isolated will enter ISOLATION when the software
" sends a WAKE[CSN] command with CSN=0.
" A card that has been isolated (i.e. CSN > 0) will enter the CONFIGURATION
" state when the software sends a WAKE[CSN] command where CSN matches the
" cards unique CSN.
" All other cards will remain in SLEEP.

" STATE: ISOLATION
" -----------------
" Unisolated cards compete to win the isolation process using their serial
" identification data.
" If a card loses during the current isolation round, it then goes back to
" the SLEEP state.
" If a card wins, it goes to WAIT FOR CSN.
" If no winner is yet assigned, the card competes in the next isolation round.

" STATE: WAIT FOR CSN
" --------------------

" unique Card Selection Number.
" After the CSN is written, the card enters the CONFIGURATION state.
state wait_csn: if (csn_wr) then config
else wait_csn;
" STATE: CONFIGURATION
" ---------------------
" A card remains in the CONFIGURATION state until the software wishes to
" wake another card (i.e. WAKE[CSN] with CSN <> card's CSN). When another
" is awakened, this card will go back into the SLEEP state because only
" one card can be in the CONFIGURATION state.

- синтаксических ошибок не выдает, но на попытку синтезирования- выдает: Execute: abl2edif.exe -a SPARTAN -o ppmain.EDN -s mod ppmain.abl, то бишь не может синтезировать файл репорта, в чем тут дело, может в настройках ? И дело даже не в коде, создаешь одновходовый элемент и тот же эффект. Если кто знает, в чем тут подвох- очень жду ответа на мыло: badlo_sergey@mail.ru.
