1) All Flash module(s) can be erased/programmed while code is executed and/or data is read from only one
Flash module or from PSRAM. The Flash module that delivers code/data can, of course, not be
erased/programmed.
2) Flash module 3 can be erased/programmed while code is executed and/or data is read from any other Flash
module.
3) Value of IMB_IMBCTRL.WSFLASH.
4) Programming and erase times depend on the internal Flash clock source. The control state machine needs a
few system clock cycles. This increases the stated durations noticably only at extremely low system clock
frequencies.
Access to the XE167xM 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.
