@item -mN
disables the generation of a NOP instruction following any instruction
that might change the interrupts enabled/disabled state. For the
MSP430x5xx series the instructions: @code{EINT}, @code{DINT}, @code{BIC
#8, SR}, @code{BIS #8, SR} and @code{MOV.W <>, SR} must be followed by
a NOP instruction in order to ensure the correct processing of
interrupts. By default generation of the NOP instruction happens
