the protection. The protection settings of the bits can be monitored by the FLCS <BLPRO> bit. See
chapter 21 for programming details.
Note) The SECBIT <SECBIT> bit is set to “1” at a power-on reset right after power-on.
Table 19-1 shows details of the restrictions by the security function.

2) Debug port
3) Command for flash memory
The TMPM330 offers two kinds of ROM protection/ security functions. One is a write/
The write/ erase-protection function enables the internal flash to prohibit the writing and erasing
This function is available with a single chip mode, single boot mode and writer mode. To activate
The security function restricts flash ROM data readout and debugging.
This function is available under the conditions shown below.
1) The SECBIT <SECBIT> bit is set to”1”.
2) All the protection bits (the FLCS<BLPRO> bits) used for the write/erase-protection function

Data in the ROM area cannot be read out when writer
mode is set. By executing readout, the company code
0x0098 is read. The ROM reading operation is available
with a single chip mode and single boot mode.
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.
