In terms of computing speed, the MSP430 series microcontroller can achieve 125ns instruction cycle driven by 8MHz crystal. 16-bit data width, 125ns instruction cycle and multi-function hardware multiplier (multiply and add) together, can achieve some algorithms of digital signal processing (such as FFT, etc.).
c. More interrupt sources
MSP430 series microcontroller has more interrupt sources and can be arbitrarily nested, flexible and convenient to use. When the system is in a power-saving standby state, it only takes 6us to wake it up with an interrupt request.
d. Ultra-low power consumption
MSP430 microcontroller has ultra-low power consumption because of its unique features in reducing the chip's supply voltage and flexible and controllable operating clock.
e. Stable system operation
After power-on reset, the CPU is first started by DCOCLK to ensure that the program starts to execute from the correct position and that the crystal oscillator has enough starting and stabilization time. Then the software can set the control bits of the appropriate registers to determine the final system clock frequency.
f. Rich on-chip peripheral modules
Members of the MSP430 series microcontroller are integrated with rich on-chip peripherals.
g. Convenient and efficient development environment
At present, the MSP430 series has three types of devices, OPT type, FLASH type, and ROM type. These devices have different development means. For OPT type and ROM type devices are developed using emulators after the successful burn-in or mask chip. FLASH type has a very convenient development and debugging environment.

How does the stack pointer work on a MSP430?
Often, as is the case with the MSP430, the stack grows downwards, that is, the stack pointer starts off pointing to the top of the stack, and with each push operation, the stack pointer decreases by 2.
How many breakpoints can mspdebug remove?
Set one more breakpoint at this address, however, in order to do so we must remove one breakpoint since mspdebug supports up to 2 breakpoints. We can delete the first breakpoint (at main) by using the following command

What is LPM3 mode?
LPM3 is the most important mode for battery-powered applications. The CPUis disabled, but enabled peripherals stay active. The basic timer provides aprecise time base. When enabled, interrupts restore the CPU, switch onMCLK, and start normal operation. Table 1–2 lists the status of the MSP430system when in LPM3.
What is active mode?
Active mode is used for calculations, decision-making, I/O functions, and otheractivities that require the capabilities of an operating CPU. All of the peripheralfunctions may be used, provided that they are enabled. The examples shownin this document use the active mode.
Does MSP430 work in LPM3?
The MSP430 system runs normally in LPM3. The enabled interrupt of the basictimer wakes the system once every second. After one minute, measurementsare made and then the system returns to LPM3. The branch to the task is madeby resetting the CPUoff bit inside the interrupt routine.
What is a bit0?
They are shortcuts for accessing specific bits in a byte/word (BIT0 is just the first bit, BIT1 the second bit, and so on). They do not really have a meaning beyond that; they are just a shorter way of writing " (1 << x) ".
Is a 16 bit mask a single bit?
No. They are bit masks of 16 bit register for single bit of the register.
