Flash Banks
| Flash Bank | Base address | Size | J-Link Support |

| Internal program flash | 0x08000000 | Up to 128KB | 
|
| Option bytes | 0x08040000 | 48 Bytes |

Option bytes
Removing the read-protection (RDP) is supported by the J-Link. Note that removing the RDP will trigger a mass-erase of the complete program flash.
Setting different protection levels (read-protection or write-protection) can be achieved with one of the following procedures:
- Program the option bytes as a part of the data/application file (Sample HEX file - RDP is set: File:AutoChips ATC0113 EVK Application Option Byte Sample.hex)
- Program the option bytes manually through the Exit steps of J-Flash: UM08003 J-Flash Exit steps
Watchdog Handling
The device has a watchdog that is fed during flash programming.
Device Specific Handling
