I see (in the definitive guide)
Reset Sequence
After the processor exits reset, it will read two words from memory:
* Address 0x00000000: Starting value of R13 (the stack pointer)
* Address 0x00000004: Reset vector (the starting address of program
execution; LSB should be set to 1 to indicate Thumb state)
The part about the LSB being set to 1 may cause difficulty! I suppose
one could say "Foo'Address + 1" (which means the vector would have to be
an array of System.Address, not so good but I think unavoidable??)
