Details

Cache corruption can occur when switching between accessing Main flash memory, and other memory regions such as NONMAIN or Calibration data areas.

Workaround

Use the following procedure to access areas outside main memory safely:

  1. Disable the cache by setting CTL.ICACHE to "0".

  2. Perform needed access to memory area.

  3. Re-enable cache by setting CTL.ICACHE to "1".
