I am using MSP430f5510 and i would like to use the JTAG Mailbox (JMB) System for Run-time data exchange.
I have looked everywhere for examples of how to use this feature, but with no luck.
Is this feature useable in MSP430f5510? If so I would be happy for some guidance of how to use it.
Thank you very much,
Yes, this can be done with MSP430F5510. Examples can be found in...

It is very simple and right way of JTAG data exchange with target device (TEST / RESET pins), but not the faster one. For max speed can be used quick read/write (IR_DATA_QUICK) because it request only one shifting per word, while mailbox system request 2 shifting per word. But of course advantage of mailbox is that target device can run free, not under JTAG control.
