18.2.1
18.2.2
The TMPM330FDFG/FYFG/FWFG offers two kinds of ROM protection/ security functions.
One is a write/ erase-protection function for the internal flash ROM data.
The other is a security function that restricts internal flash ROM data readout and debugging.

for programming details.
The write/ erase-protection function enables the internal flash to prohibit the writing and erasing operation for
To activate the function, write "1" to the corresponding bits to a block to protect. Writing "0" to the bits cancels
The protection settings of the bits can be monitored by the FCFLCS <BLPRO[5:0]> bit. See the chapter "Flash"
The security function restricts flash ROM data readout and debugging.
This function is available under the conditions shown below.
Table 18-1 shows details of the restrictions by the security function.

Security function
Note:The FCSECBIT <SECBIT> bit is set to "1" at a power-on reset right after power-on.
Note:The TMPM330FYFG is configured with block 2 through 5. Block 0 and 1 require a programming

Item
Data can be read from CPU.
Communication of JTAG/SW and trace are prohibited
Writing a command to the flash memory is prohibited.
An attempt to erase the contents in the bits used for the write/erase-
protection erases all the protection bits.
