Remapping interrupts to RAM

Cactus Blip

Hello,
I am mapping interrupts to RAM (MEMMAP = 2). I want to overwrite some of the contents of 0x40000000 with my own address (namely, 0x40000008, that is the SWI handler). I know what I want: I need to install a branch instruction like

LDR PC, SWI_Handler


But when I look at address 0x0 (just for an example of how it is done in flash), I see the following repeating pattern:

0x0 18F09FE5
0x4 18F09FE5
0x8 18F09FE5
0xC 18F09FE5

I would expect to find there different instructions!
What gives?
