Figure 5-6 BSL Connection Schematic

Detailed description of the BSL connection can be found in MSP430 Programming With the Bootloader (BSL) (SLAU319). It is important to note that the MSP-GANG Programmer's Fast-BSL has much higher communication speed than standard BSL, 200 kbps compared to 9.6 kbps. Consequently, ensure that the hardware does not have additional delay on the BSL RX and TX lines beyond 0.5 µs (a clock pulse duration of 2 µs must be transmitted by the BSL RX and TX lines without degradation). Any additional filters or suppressors on the BSL RX and TX lines can degrade communication.
