19.4.4
On each reset, the Flash module executes a reset sequence to hold CPU activity while loading the following
registers from the Flash array memory according to
19.4.4.1
If a reset occurs while any Flash command is in progress, that command will be immediately aborted. The
state of the word being programmed or the sector/array being erased is not guaranteed.
19.4.5
The Flash module can generate an interrupt when all Flash commands have completed execution or the
Flash address, data, and command buffers are empty.
19.4.5.1
Figure 19-29
The Flash module uses the CBEIF and CCIF flags in combination with the enable bits CBIE and CCIE to
discriminate for the generation of interrupts.
