Parameter
Number of erase cycles
1) All Flash module(s) can be erased/programmed while code is executed and/or data is read from only one Flash
2) Flash module 1 can be erased/programmed while code is executed and/or data is read from Flash module 0.
3) Value of IMB_IMBCTRL.WSFLASH.
4) Programming and erase times depend on the internal Flash clock source. The control state machine needs a
Access to the XC223[04]L Flash modules is controlled by the IMB. Built-in prefetch
mechanisms optimize the performance for sequential access.
Flash access waitstates only affect non-sequential access. Due to prefetch
mechanisms, the performance for sequential access (depending on the software
structure) is only partially influenced by waitstates.
