-  - Boot0: TRAP isr for load boot1
+  - Boot0: Reset/TRAP isr for load boot1
   - Boot1: Minimal bootloader stored in *reserved* option bytes
   - Boot2: Full-featured bootloader loaded via serial communication

+## Bootloader Integration
+
+1. The main application includes `bootloader.h`, which redirects the TRAP interrupt vector to `bootloader_enter()` in `bsp/boot0.c`.
+
+2. During the build process, the Makefile swaps the reset vector (0x8000) and trap vector (0x8004) positions. This ensures that upon startup, the bootloader entry routine executes first.

 ## Option Bytes Configuration
 
 The bootloader uses the reserved option byte area for storage:
