(1) Refer to the device-specific data sheet for the available TI BSL protocol on these devices. TI provides a specific BSL protocol for each flash device.
(2) BSL in flash memory allows to replace the BSL with a custom version.
(3) The USB-to-Serial Converter is compatible with BSLDEMO. The invocation signal is generated on the DTR pin for the RESET pin, and on the RTS pin for the TEST pin.
(4) All BSL software collateral (application, examples, source code, and firmware images) is available in the BSL tool folder.
The MSP430 USB developers package includes additional USB BSL sample applications.
(5) F543x (non A) has a 16-byte password.
(6) Some devices can disable mass erase on incorrect password. See the device family user's guide.
(7) Firmware validation through CRC.
