SLAS703C April 2010 – September 2020 MSP430BT5190
The BSL enables users to program the flash memory or RAM using a UART serial interface. Access to the device memory through the BSL is protected by an user-defined password. Usage of the BSL requires four pins as shown in Table 8-3. BSL entry requires a specific entry sequence on the RST/NMI/SBWTDIO and TEST/SBWTCK pins. For further details on interfacing to development tools and device programmers, see the MSP430 Hardware Tools User's Guide (SLAU278). For a complete description of the features of the BSL and its implementation, see the MSP430 Programming Via the Bootstrap Loader User's Guide (SLAU319).
