MSP430G2755: Spy-Bi-Wire and JTAG

Part Number: MSP430G2755
Other Parts Discussed in Thread: MSP430G2553, MSP-FET

HI,

     Please help to confirm, thank you.

1. Does it support MSP430G2553 LaunchPad Board connection to use Spy-Bi-Wire (SBW)? See application report SLAA754.
2. Does it support 2-wire JTAG programming and debugging signal connection? Please refer to "MSP430™ Hardware Tools User Guide" 
3. If XIN and XOUT are not used, are they set to GPIO or need to be pull-low to gnd?

    Yes. It supports the SBW.

    Yes. This diagram is the JTAG connector on which the SBW signals also available. It is on the MSP-FET programmer/debugger connector. This connector is different from the LaunchPad connector definition. But the SBW is available on both.

    By default after power-on, P2SEL.6=0, P2SEL2.6=0, P2SEL.7=0, P2SEL2.7=0, the P2.6, P2.7 are GPIO functionality. No need to pulled low to GND. But if we don't need to use these 2 GPIO pins, you can set them to output low to save power consumption.
