FLASHDOZE
Flash Doze
When set, Flash memory is disabled for the duration of Wait mode. An attempt by the DMA or other bus
master to access the Flash when the Flash is disabled will result in a bus error. This bit should be clear
during VLP modes. The Flash will be automatically enabled again at the end of Wait mode so interrupt
vectors do not need to be relocated out of Flash memory. The wakeup time from Wait mode is extended
when this bit is set.
0 Flash remains enabled during Wait mode
1 Flash is disabled for the duration of Wait mode
0
FLASHDIS
Flash Disable
Flash accesses are disabled (and generate a bus error) and the Flash memory is placed in a low power
state. This bit should not be changed during VLP modes. Relocate the interrupt vectors out of Flash
memory before disabling the Flash.
0 Flash is enabled
1 Flash is disabled
