It loads the CEM flash dump and reads the PIN at fixed offset. You can find the pin yourself if you have a dump.

Here's a pin from 2005 XC70 dump (327680 bytes), at offset 0x4E000: 1.png Thank you. Address 0x4E000 blank, all FF's. This CEM has MC32 MCU, can't seem to find the location for those. I used Autel programmer, VVDI failing to read this mcu. I have feeling it doesn't do a complete read. I've read 2 d...

M32C comes in different Flash sizes.

320kB starts at 0xFB0000 with size 0x50000
384kB starts at 0xFA0000 with size 0x60000
512kB starts at 0xF80000 with size 0x80000

From the CPUs point of view, the pin is typically 0x2000 from the end at 0xFFE000.
