Protection MMR. Controls read and write protection of the Flash/EE memory code space. If previously configured via
the FEE0PRO register, FEE0HID can require a software key to enable access.
A buffer of the FEE0HID register that stores the FEE0HID value, so it is automatically downloaded to the FEE0HID
registers on subsequent reset and power-on events

Read/Write Access
This 8-bit register is written by user code to control the operating modes of the Flash/EE memory controller.
Description
Reserved, this command should not be written by user code
Load FEE0DAT with the 16-bit data indexed by FEE0ADR
Write FEE0DAT at the address pointed by FEE0ADR. This operation takes 50Ps.
Erase the page indexed by FEE0ADR and write FEE0DAT at the location pointed by FEE0ADR. This operation
takes 20ms
Compare the contents of the location pointed by FEE0ADR to the data in FEE0DAT. The result of the comparison
is returned in FEE0STA bit 1
Erase the page indexed by FEE0ADR
Erase 30kBytes of user space. The 2kByte Kernel is protected. This operation takes 1.2s To prevent accidental
execution, a command sequence is required to execute this instruction, this is described below.
Default command.
Reserved, this command should not be written by user code
Reserved, this command should not be written by user code
Reserved, this command should not be written by user code
This command will result in a 24-bit LFSR based signature been generated and loaded into FEE0SIG.
If FEE0ADR is less than 0x87800, this command will result in a 24-bit LFSR based signature of the user code
space from the page specified in FEE0ADR upwards, including the Kernel, security bits and Flash/EE key.
If FEE0ADR is greater than 0x87800, the Kernel and manufacturing data is signed. This operation takes 120us.
This command can be run only once. The value of FEE0PRO is saved and can be removed only with a mass erase
(0x06) or with the key
Reserved, this command should not be written by user code
Reserved, this command should not be written by user code
No operation, interrupt generated
