{ On-chip debug operation control

• Enabling on-chip debug operation and erasing data of the flash memory in case authentication of the on-
chip debug security ID fails
• Enabling on-chip debug operation and not erasing data of the flash memory even in case authentication of
the on-chip debug security ID fails
