Note:
1. The parameters in the figure above are given in Table 100 on page 257.
Boot Loader Lock
Bits
If no Boot Loader capability is needed, the entire Flash is available for application code. The
Boot Loader has two separate sets of Boot Lock bits which can be set independently. This gives
the user a unique flexibility to select different levels of protection.
The user can select:
•
To protect the entire Flash from a software update by the MCU
•
To protect only the Boot Loader Flash section from a software update by the MCU
•
To protect only the Application Flash section from a software update by the MCU
•
Allow software update in the entire Flash
See Table 96 and Table 97 for further details. The Boot Lock bits can be set in software and in
Serial or Parallel Programming mode, but they can be cleared by a Chip Erase command only.
The general Write Lock (Lock Bit mode 2) does not control the programming of the Flash mem-
ory by SPM instruction. Similarly, the general Read/Write Lock (Lock Bit mode 3) does not
control reading nor writing by LPM/SPM, if it is attempted.
