2.5.1 Flash Multi Page Erase Non-Functional from UPDI

Performing a Flash multi-page erase (writing the CMD bitfield in NVMCTRL.CTRLA to FLMPERn) from UPDI does not work on the boot section. It is not recommended to use multi-page erase on any Flash section.

Work Around

Use Flash page erase (writing the CMD bitfield in NVMCTRL.CTRLA to 0x08).
