Bit 1 – BOOTLOCK: Boot Section Lock

Writing a '1' to this bit locks the boot section from read and instruction fetch.

If this bit is '1', a read from the boot section will return '0'. A fetch from the boot section will also return 0

as instruction.

This bit can only be written from the boot section. It can only be cleared to '0' by a Reset.

This bit will only take effect when the boot section is left the first time after the bit is written.

Bit 0 – APCWP: Application Code Section Write Protection

Writing a '1' to this bit protects the application code section from further writes.

This bit can only be written to '1', it is cleared to '0' only by Reset.
