Bootloader (BSL)
The MSP430 BSL enables users to program the flash memory or RAM using a UART serial interface.
Access to the MSP430 memory through the BSL is protected by user-defined password. For complete
description of the features of the BSL and its implementation, see the
MSP430 Programming With the
Bootloader User's Guide
(
SLAU319
).
Table 6-9
lists the BSL function pins.
