to program the 2329 I use the the App125
document, using the routines related to 0.35um, is this correct routines to program H8s/2329 ? .
: It sounds like your code did not
: program the flash correctly. Did
: you remember to use the
: program-verify feature of the
: programming algorithm and the
: erase-verify feature of the erase
: algorithm. If the contents were not
: versified correctly as given in the
: algorithm the data retension cannot
: be assumed to be that specified in
: the hardware manual. Also check
: that the re-program and additional
: re-program data is being correctly
: calculated. Apps note 125 from the
: link below should help.

: I made a program on 2329 boards, to
: manage a message display leds, this
: program has a feature that allows to
: change firmware at run time, erasing

: cpus), and now, 6 mounths later 50

: do you know why flash lost its data?
