Digging the Jerry source code and using the mandel.cof example (provided from #52), I've found a weird issue.

Line:
004038: 23FC 0000 3F00 00F1 0020 MOVE.L #$3F00, JINTCTRL

JINTCTRL ($F10020), Interrupt Control Register, is a 16 bits register.
But $F10022 doesn't exist in the documentation, and I guess the console shouldn't react to any value.

VJ considers both address to handle the Interrupt Control Register, but it should not be the case if we follow the 'documentation'.
