4.3 Flash Security
How flash security is implemented on this device is described in

4.4 Flash Modes

The flash memory is always configured in NVM normal. There are no operating
conditions in which the flash is configured for NVM special mode.

4.5 Erase All Flash Contents

An Erase All Flash Blocks operation can be launched by software through a series of
peripheral bus writes to flash registers. In addition the entire flash memory may be erased
external to the flash memory from the SWJ-DP debug port by setting
DAP_CONTROL[0]. DAP_STATUS[0] is set to indicate the mass erase command has
been accepted. DAP_STATUS[0] is cleared when the mass erase completes.
