Advance Information

Once the FLASH has been programmed with application code, the MCU
can be secured by programming the security bytes located in the SGFM
configuration field. These non-volatile bytes will keep the MCU secure
through reset and power down. Only two bytes within this field are used
to enable or disable security. Refer to the
Generation FLASH for M•CORE (SGFM)
bytes and the resulting state of security.
When FLASH security is enabled, the MCU will boot only in single-chip
mode and will fetch its reset vector from address 0x0000_0000 of the
on-chip FLASH. The M•CORE CPU will fetch and execute opcodes from
the on-chip FLASH or on-chip SRAM if user code is copied there. Normal
program execution is not affected by enabling FLASH security.
M•CORE microcontrollers have several operating functional and test
modes. Effective FLASH security must address operating mode
selection and anticipate modes in which the on-chip FLASH can be
compromised and read without explicit user permission. Blocking the
two currently identified means for doing this are outlined in the
subsections that follow.
The chip configuration module (CCM) determines, at boot time, in which
of the four functional modes the MCU will operate. These modes are:
