ISR and Halt on an ARM

Started by Raul August 11, 2005
Is there a way for an ISR to disable the halt instruction on an ARM
once the micro-controller embarks upon the perilous path to Halt?

No. Mostly because there is no halt instruction in ARM instruction set. What documentation are you using? Vadim
Thanks for the reply.  I am working on a TMS470 which is based on an
ARM core.  Halt is achieved by writing a specific value to the CLKCNTL
register.
