MSP430FR5859: MSP430FR5859 , detailed description of IP encapsulation

Part Number: MSP430FR5859

Hi,

We have got a problem with customers data when JTAG access to device is disabled after programming customer's file (no JTAG fuse mode neither JTAG password mode were programmed/allowed).

We guess that the JTAG access is disable by data programmed in FRAM, we deduced it from sentence "Must not contain 0AAAAh if used as JTAG password and IP encapsulation functionality is not desired" in the device datasheet. But there is missing detailed description of the IP encapsulation functionality. Could you let me know where I can find detailed description of the IP encapsulation functionality or can you send me one?

Thank you in advance.

Best regards,
Frantisek
