How data is stored in memory is related with endianess. MSP430 is little endian, so the “end” (LSB) is stored in the “little” address. So if you store a 32 bit value in address 0x300, MSB will be in 0x303 and LSB will be in 0x300. Some MSP430 have a CPUx instead a CPU “core”, and they are able to address a 20 bit width address bus.

TI MSP430. Instructions are 16 bits, followed by up to two 16-bit extension words. Addressing modes are specified by the 2-bit As field and the 1-bit Ad field. Some special versions can be constructed using R0, and modes other than register direct using R2 (the status register) and R3 (the constant generator) are interpreted specially.

The MSP430’s powerful 16-bit RISC core offers many advan-tages over competing 4- and 8-bit microcontrollers. The MSP430 CPU features the ease of use of a RISC instruction set and the flexibility of numerous 16-bit CPU registers. These and other features result in a revolutionary architecture that is highly orthogonal by design. The MSP430 has a RISC instruction set that consists of a
MSP430 Microcontroller Basics distinct instructions. In many ways these features make the 16-bit MSP430 simpler than a typical 8-bit processor.
This is one of the important features of the MSP430 instruction set, All instructions are 16 bits long, and there are only three instruction formats:
Note: it is required that you are familiar with the MSP430 instruction set and addressing modes to be able to solve this problem. We assume that the string is no longer than 255 characters, so the result can be displayed on an 8-bit port. 2. Count Characters: Assembly Code Figure 1 …

ESE101: MSP430 Introduction. How Many Bits? Originally the MSP430 was a “true” 16-bit microcontroller, The MSP430 has 27 instructions.
If the bit is set then the pin is an output, if the bit is clear then the pin is an input. As with the pin numbers, bit numbers in a register always begin with 0; 8 bit registers are 0-7 and 16 bit registers are 0-15. You will often need to speficy a register bit in the operand of a machine instruction.
B/W is a bit that is set to 1 for byte instructions. 2-operand opcodes begin at 0100 = 4. As you can see, there are at most 8+8+12 = 28 instructions to keep track …
