Offset | Type | Description |
---|---|---|
0xF50 | u32[10] | SVC mode registers, r4-r11, r13, r14 |
0xFF8 | u32 | FPEXC, floating point exception register for thread- stored and loaded on context switches |

- Save the LR to r1- this LR is the return back to the main scheduling and context switching function
- Load r4-r11, SP, LR
- Branch back to r1, preserving the LR which was just reloaded, back to the main scheduling function, but in the context of the newly switched-to thread
