PPT-LAB 4: Interrupt

ChungTa King National Tsing Hua University CS 4101 Introduction to Embedded Systems Introduction In this lab we will learn The interrupt of TimerA in MSP430 The interrupt of port P1 in MSP430. 256 interrupt disable interrupt enable 3520 How can I be sure that general interrupts will not be enabled too early Example function1 DINT GIE flag clear will disable general interrupts function2 A call to function2 EINT The final GIE flag set Bruce Worthington.
