Backdoor access key implementation in S32K116

[prabhatg44]

Thanks for the code, I was trying to set the Backdoor access key by modifying steps in startup_S32K116.s file as below to set FSEC register:

BackDoorK0 EQU 0x10
BackDoorK1 EQU 0x32
BackDoorK2 EQU 0x54
BackDoorK3 EQU 0x76
BackDoorK4 EQU 0x98
BackDoorK5 EQU 0xBA
BackDoorK6 EQU 0xDC
BackDoorK7 EQU 0xFE

; <3=> Backdoor key access disabled
; <i> Backdoor Key Security Enable
FSEC EQU 0xBE

But not able to see BF value in the debugger. Can you please support me in this regards.
