* The main problem with crashing is that you can't do anything without disturbing registers,
|
||||
* and if you disturb registers, you won't be able to see the correct register values in the debugger.
|
||||
*
|
||||
* Current solution works around it by passing the message through r12 and doing some magic with registers in crash function.
|
||||
* r0-r10 are stored in the ram2 on crash routine start and restored at the end.
|
||||
* The only register that is going to be lost is r11.
