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. Table 6-9. BSL Function Pins BSL FUNCTION 20-PIN PW PACKAGE 20-PIN N PACKAGE 28-PIN PW PACKAGE 32-PIN RHB PACKAGE Data transmit 3 - P1.1 3 - P1.1 1 - P1.1 Data receive 7 - P1.5 7 - P1.5 5 - P1.5 |
