EINT Enable Maskable Interrupts (Clear INTM Bit)
SYNTAX OPTIONS OPCODE OBJMODE RPT CYC
EINT 0010 1001 0001 0000 X − 2

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)
