Writing and erasing
When the settings for all the blocks are "1", erasing must be done after setting the FCSECBIT <SECBIT> bit to
"0". Setting "1" at that situation erases all the protection bits. To write and erase the protection bits, command
sequence is used.
power-on.
Writing and erasing protection bits are available with a single chip mode, single boot mode and writer mode.
Writing to the protection bits is done on block-by-block basis.
Erasing of the protection bits is done by two groups of the blocks: block 0 through 3 and block 4 through 5.
See the capter "Flash" for details
The FCSECBIT <SECBIT> bit that activates security function is set to "1" at a power-on reset right after
The bit is rewritten by the following procedure.
Protection bits
Security bit
Note:The above procedure is enabled only when using 32-bit data transfer command.
1. Write the code 0xa74a9d23 to FCSECBIT register.
2. Write data within 16 clocks from the above.1.
