Instruction Set Description

4.6.4 MSP430X Address Instructions

MSP430X address instructions are instructions that support 20-bit operands but have restricted

addressing modes. The addressing modes are restricted to the Register mode and the Immediate mode,

except for the MOVA instruction. Restricting the addressing modes removes the need for the additional

extension-word op-code, which improves code density and execution time. The MSP430X address

instructions are described in the following sections.

See Section 4.6.3 for MSP430X extended instructions and Section 4.6.2 for standard MSP430

instructions.
