Enable interrupts by clearing the INTM status bit.
Flags and
Modes
INTM
This bit is cleared by the instruction to enable interrupts.
Repeat
This instruction is not repeatable. If this instruction follows the RPT
instruction, it resets the repeat counter (RPTC) and executes only once.
Example
; Make the operation ”VarC = VarA + VarB” atomic:
DINT
; Disable interrupts (INTM = 1)
MOVL ACC,@VarA
; ACC = VarA
ADDL ACC,@VarB
; ACC = ACC + VarB
MOVL @VarC,ACC
; Store result into VarC
EINT
; Enable interrupts (INTM = 0)
