6.5.3 Single Chip Boot Mode
In single chip mode the hardware searches flash boot sector for a valid boot ID. As soon the device detects
a bootable sector, it jumps within this sector and reads the 32-bit word at offset 0x4. This word is the
address where the startup code is located (reset boot vector).
