+All members of the SAM E54, E53, E51 and D51 microcontroller
+families from Microchip (former Atmel) include internal flash
+and use ARM's Cortex-M4 core.
+
+The devices have two ECC flash banks with a swapping feature.
+This driver handles both banks together as it were one.
+Bank swapping is not supported yet.

+@end example
+
+@deffn Command {atsame5 bootloader}
+Shows or sets the bootloader size configuration, stored in the User Page of the
+Flash. This is called the BOOTPROT region. When setting, the bootloader size
+must be specified in bytes. The nearest bigger protection size is used.
+Settings are written immediately but only take effect on MCU reset.
+Setting the bootloader size to 0 disables bootloader protection.

+
+@deffn Command {atsame5 chip-erase}
+Issues a complete Flash erase via the Device Service Unit (DSU). This can be
+used to erase a chip back to its factory state and does not require the
+processor to be halted.
+@end deffn
+
+@deffn Command {atsame5 dsu_reset_deassert}

+
+@deffn Command {atsame5 userpage}
+Writes or reads the first 64 bits of NVM User Page which is located at
+0x804000. This field includes various fuses.
+Reading is done by invoking this command without any arguments.
+Writing is possible by giving 1 or 2 hex values. The first argument
+is the value to be written and the second one is an optional bit mask
+(a zero bit in the mask means the bit stays unchanged).
+The reserved fields are always masked out and cannot be changed.

+@example
+# Read
+>atsame5 userpage
+USER PAGE: 0xAEECFF80FE9A9239
+# Write
+>atsame5 userpage 0xAEECFF80FE9A9239
+# Write 2 to SEESBLK and 4 to SEEPSZ fields but leave other bits unchanged
+# (setup SmartEEPROM of virtual size 8192 bytes)
