Disable all maskable CPU interrupts by setting the INTM status bit. DINT has
no effect on the unmaskable reset or NMI interrupts.
The instruction sets this bit to disable interrupts.
This instruction is not repeatable. If this instruction follows the RPT
instruction, it resets the repeat counter (RPTC) and executes only once.
