Hi, team:

     I want to confirm the security interaction with debug. 

    In S32K1xx Series Safety Manual , JTAGC TAP is disabled by pull JTAG_TMS low.

   and in the reference manual, the debugging capabilities are disabled when flash memory security is active.

i want to know if "JTAGC TAP disabled" is equivalent to "debugging capabilities"? the chip is S32K144, flash security is active and mass erase disabled.
