I am using ARM Cortex R4F core and i want to know about the J bit in the CPSR/SPSR Field.
What is the purpose if this bit?
As per the Document, we can read the J bit value as 0. Is this condition is always true?
And if i want to enable this bit, How can i do that?
Can anyone please explain me this?
Seems clear enough:
It's a bit that reads as zero.
Putting "Cortex R4F J bit CPSR/SPSR" into google also gives:
Which suggest that it would only be '1' if the Jazelle instruction set were present
