Hello,
This is not a Keil specific question, but I was hoping that somebody would be able to clarify the following as I don't have a lot of experience with Cortex M0 chips (I have a LPC1114 at my disposal):
I understand that unlike Cortex M3s, a Cortex M0 always runs in privileged mode. Therefore,
__disable_irq() ;
always disables the interrupts.
What is then the purpose of the SVC instruction on a Cortex M0? It is supposed to switch the core to a privileged mode just like a ARM7's SWI instruction, but apparently it is not necessary...? If so, I also don't need to do anything special when jumping from a bootloader to the application (in terms of processor mode), right?
