In start167.a66 file, I find following assembler instruction:
MOV STKOV,#(_BOS+6*2) ; INITIALIZE STACK OVFL REGISTER
Why the 6*2?
I could understand 4*2 because of automatic push/pop of PSW, CSP and IP (when interrupting) and one extra because of non-inclusive aspect.
Can anyone give explanation or reference to a manual?
Thanks, Bjorn
