Q.
How should I describe the C-source statements to avoid getting the ln30 warning error "JMP.S instruction exist at end of bank
(address xxxxx)"?
A.
Use assembler-command instruction ".SJMP" so that the assembler does not output the jmp.s instruction
To disable the jmp.s instruction output: .SJMP OFF
To enable the jmp.s instruction output: .SJMP ON
Enclose the area that generated the warning as follows: ".SJMP OFF" and ".SJMP ON"
[Example Declaration]
main()
{
asm(" .SJMP OFF"); //disable jmp.s instruction
if(xxxxx)
...... //area that generated warning
else
.......
asm(" .SJMP ON"); //enable jmp.s instruction
}
