What's the shortest code to cause a stack overflow? [closed]
...LL (relative call) is smaller still (not global memory, so no need for the extra 2 bytes):
RCALL $
1101 1000 0000 0000
So the smallest on the PIC18 is a single instruction, 16 bits (two bytes). This would take 2 instruction cycles per loop. At 4 clock cycles per instruction cycle you've got 8 c...
