Hello,
I have programmed the shadow flash private password to 01234567 89abcdef on my MPC5606B MCU. I also wrote both censorship control words to 0xFFFF, which enables the public password and censors the device. I have been able to verify this. However, the datasheet also states this:
"In order to unsecure the device, the password needs to be written as follows: first the upper word to the
SSCM_PWCMPH register, then the lower word to the SSCM_PWCMPL register. The SSCM compares
the 64-bit password entered into the SSCM_PWCMPH / SSCM_PWCMPL registers with the
NVPWM[1,0] private password stored in the shadow flash. If the passwords match then the SSCM
temporarily uncensors the microcontroller."
When I do this in BAM mode, nothing seems to happen. Is this normal? Can I still access the device through JTAG and the private password?
Thanks
Hi, I have example code for censorship here:

Password needs to be entered in reverse, in your case 89abcdef 01234567
