27.1 On-Chip Debug Security ID
µ
The PD78F0537D has an on-chip debug operation control flag in the flash memory at 0084H (see CHAPTER 25
OPTION BYTE) and an on-chip debug security ID setting area at 0085H to 008EH.
When the boot swap function is used, also set a value that is the same as that of 1084H and 1085H to 108EH in
advance, because 0084H, 0085H to 008EH and 1084H, and 1085H to 108EH are switched.
For details on the on-chip debug security ID, refer to the QB-78K0MINI User's Manual (U17029E).
