Flash/EE Interrupt Enable.
Erase/Write Command Protection.
Reserved. Always set these bits to 0.
Set by user to enable the Flash/EE interrupt. The
interrupt occurs when a command is complete.
Cleared by user to disable the Flash/EE interrupt.
Set by user to enable the erase and write commands.
Cleared to protect the Flash against erase/write

Description
Idle State.
Load FEEDAT with the 16-bit data. Indexed by FEEADR.
Write FEEDAT at the address pointed by FEEADR. This operation takes 50 μs.
Erase the page indexed by FEEADR and write FEEDAT at the location pointed by FEEADR. This
operation takes approximately 24 ms.
Compare the contents of the location pointed by FEEADR to the data in FEEDAT. The
result of the comparison is returned in FEESTA Bit 1.
Erase the page indexed by FEEADR.
Erase 30 kB of user space. The 2 kB of kernel are protected. To prevent accidental
execution, a command sequence is required to execute this instruction. See the
Command Sequence for Executing a Mass Erase section.

This command results in a 24-bit LFSR based signature been generated and loaded into
FEESIG MMR. This operation takes 16,389 clock cycles.
This command can run only once. The value of FEEPRO is saved and removed only with a
mass erase (0x06) or the key.
