Notes
9. For the full temperature range, the user must employ a temperature sensor user module (FlashTemp) or other temperature sensor, 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.
10. The maximum total number of allowed erase/write cycles is the minimum Flash
ENPB
value multiplied by the number of flash blocks in the device.
