FLASH/EE MEMORY SECURITY
The 62 kB of Flash/EE memory available to the user can be
read- and write-protected using the FEEHID register.
The MSB of FEEHID (Bit 31) protects the entire Flash/EE from
being read through JTAG.
Bits[30:0] of FEEHID protect Page 123 to Page 0 from writing.
Each bit protects four pages, that is, 2 kB. On the 30 kB version,
Bits[30:15] are unused.

Description
Read protection.
This bit is cleared by user code to read protect the 62 kB Flash/EE block code.
This bit is set by user code to allow read access to the 62 kB Flash/EE block via JTAG.
Write protection bits.
When set by user code, these bits unprotect Page 0 to Page 123 of the 62 kB Flash/EE code memory. Each bit write
protects four pages, and each page consists of 512 bytes.
When cleared by user code, these bits write protect Page 0 to Page 123 of the 62 kB Flash/EE code memory. Each bit
write protects four pages, and each page consists of 512 bytes.
FEEHID and FEEPRO
0xFFFF0E20 (for FEEHID) and 0xFFFF0E1C (for FEEPRO)
0xFFFFFFFF (for FEEHID) and 0x00000000 (for FEEPRO)
Read/write
These registers are written by user code to configure the protection of the Flash/EE memory.
Rev. B | Page 21 of 92
The FEEPRO register mirrors the bit definitions of the FEEHID
MMR. The FEEPRO MMR allows user code to lock the pro-
tection or security configuration of the Flash/EE memory so
that the protection configuration is automatically loaded on
subsequent power-on or reset events. This flexibility allows
the user to temporarily set and test protection settings using
the FEEHID MMR and, subsequently, lock the required
protection configuration (using FEEPRO) when shipping
protection systems into the field.
