blocks of 50,000 maximum cycles each, 36x2 blocks of 25,000 maximum cycles each, or 36x4 blocks of 12,500
maximum cycles each (to limit the total number of cycles to 36x50,000 and that no single block ever sees more
than 50,000 cycles).
For the full industrial range, the user must employ a temperature sensor user module (FlashTemp) and feed the
result to the temperature argument before writing. Refer to the Flash APIs Application Note AN2015 at
http://www.cypress.com under Application Notes for more information.
