In which mode of MSP430 all clocks are disabled?
Explanation: LPM4 is known as the RAM retention mode. Here, the CPU and all clocks are disabled, I ≈ 0.1A. The device can be woken only by an external signal.
What is difference between CISC and RISC?
One of the major differences between RISC and CISC is that RISC emphasizes efficiency in cycles per instruction and CISC emphasizes efficiency in instructions per program. … RISC needs more RAM, whereas CISC has an emphasis on smaller code size and uses less RAM overall than RISC.
Does the MSP430 microcontroller support real time clock please explain?
All MSP430 devices contain both a digitally-controlled RC-type oscillator and a crystal oscillator. … In the real-time clock application, the crystal oscillator is used as the clock source for the timer/counter that serves as the time base (either Timer_A or the Watchdog Timer in this application report).

What is the size of data bus of MSP?
The MSP-430 is a 16-bit microcontroller. It has a 16-bit address bus and a 16-bit data bus. It can address 64K address locations as byte-addressable memory. That memory holds the program and the data.
What is information memory in MSP430?
All MSP430 devices also have some smaller 64-byte or 128-byte flash segments. This area of the flash is called the information memory. In most applications, the main memory stores program code and constant data values, and the information memory is used for calibration data, serial numbers, etc.
What is the difference between microprocessor and microcontroller?
