Debug Operation
When run-time debugging, this peripheral will continue normal operation. Halting the CPU in debugging
mode will halt normal operation of the peripheral.
If the peripheral is configured to require periodical service by the CPU through interrupts or similar,
improper operation or data loss may result during halted debugging.

Flash
The Flash is divided into a set of pages. A page is the basic unit addressed when programming the Flash.
It is only possible to write or erase a whole page at a time. One page consists of several words.
The Flash can be divided into three sections in blocks of 256 bytes for different security. The three
different sections are BOOT, application code (APPCODE) and application data (APPDATA).
