The MSP432™ uses a additional level for interrupts: the Nested Vectored Interrupt Controller (NVIC). Every interrupt you request must be enabled in the NVIC. To enable for example the Timer_A0_N interrupt you have to call also the NVIC function: Jan 04, 2016 · With all that settings we have 1 second delay (on the video we can see 0.999 second with a logic analyzer). Low-power mode and interruption. In order to have a system with a low-power mode, we set it with LPM0_bits and we enable the Global Interrupt Enabled (GIE). So each time the counter reach the value 24198, it will trigger an interruption. msp432 startup code.

Page 424 of MSP432 Technical Reference Manual (pdf) We can add the following code before the SysTick configuration to enable the low power mode.Holds the system core clock, which is the system clock frequency supplied to the SysTick timer and the processor core clock. This variable can be used by debuggers to query the frequency of the debug timer or to configure the trace clock speed. \$\begingroup\$ Depends on the instruction, optimization, compile options or language, but an intrinsic like __delay_cycles is highly optimized for that purpose, as well as "nops" (1 cycle). Higher order math take more, math involving things outside of 2/4/8/16 take more. SysTick operation is specified in Section B3.3 of the "ARMv6-M Architecture Reference Manual." SysTick Operation. The system timer consists of four registers (CTRL, LOAD, VAL, CALIB) which are defined in the CMSIS-Core header file core_cm0plus.h.
