Bootstrap Loader (BSL)

NOTE

Devices from TI come factory programmed with either an I2C-based BSL or a timer-based

UART BSL. Refer to Table 1 to determine which BSL type is implemented.

Bootstrap Loader - I2C

The I2C BSL enables users to program the flash memory or RAM using a I2C serial interface. Access to the

device memory via the BSL is protected by an user-defined password.

When using the BSL, it requires a specific entry sequence on the RST/NMI and BSLEN pins. Table 6 shows the

required pins and their functions. 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).

NOTE

To invoke the BSL from the DVIO domain, the RST/NMI and BSLEN pins must be used

for the entry sequence. It is critical not to confuse the RST/NMI pin with the

RSTDVCC/SBWTDIO pin. In other MSP430 devices, SBWTDIO is shared with the

RST/NMI pin and RSTDVCC does not exist. Additional information can be found in

Designing with MSP430F522x and MSP430F521x Devices (SLAA558).
